I came for the sweet 80s soundtrack but ended up getting pretty invested in the build so I hung around to the end.
Im glad I did cuz Ivan giggles are the best. 😄
I was going to be a DJ but then I bought a 3D printer and you know the rest…
It's truly exciting to see and Ivan Miranda project come together!
His channel is larger than life! These videos are outstanding!
The real shame here is that we have this big beautiful printer and such a variety of nice filament out there but all we see is red over and over and over and over again.
@Jack_Waffles maybe it's a trademark
The tires held up much better than I thought. Although, maybe they need to be a little thicker to give you some ground clearance? Also, maybe the front wheels just need a wider axle? You might save some weight by removing a couple of vertical bars in the frame, but I'm not sure how much rigidity you'd lose from that. Always impressed by your ability!
Love it. Well done; looking forward to the race.
Thanks Neil!
You should invert the screw direction to prevent it from coming loose while moving forward. You want a counter clockwise screw so that it will stay tight as the wheel moves in the counter clockwise direction.
They are all threaded to tighten as the kart moves forward, if you watch, the right side he tightens going clockwise, and the left counter clockwise.
@@nicholasdowns3502 didn't realize, sorta jumped to conclusions lol
Correct, all right side nuts are righty tighty and the left hand side lefty tighty. I’m sure I neglected to fasten that one and checking the wheel nuts wasn’t in the pre-race checklist. Also making a pre-race checklist wasn’t on my TO-DO list and I don’t use TO-DO lists so it was bound to happen.
@@ivanmirandawastaken noice 👍🏼
@@ivanmirandawastaken Here is the challenge "3d printed speed boat" ) Greetings from Ukraine !
Awesome as always man!
What an incredible build! =D
Thanks!
Just amazing.
Wow I want to try this! 😮
It occurred to me that 65 kg overall weight is essentially 65 spools of filament. At least for us peasants who don't buy in bulk. That alone is mind boggling. The fact that you have a drivable prototype that didn't collapse on the first test is just awesome. Looking forward to the race! Thanks for sharing!
That’s over 1500$ worth of filament!
the front wheels came undone because the wheel essentially loosened the nut at that speed, which made it come loose. having the nuts tighten with the rotation direction of the wheels prevents that
They do already tighten with the tire rotation, the thread pitch might just be too steep
He has done that. Watch video again. The right side was just loos when he started.
It's amazing and so fun!
This is amazing, my 4 year old son and I love watching this series. Thank you.
Awesome project. Look forward to the upgraded parts.
Watching you build stuff is ASMR for me.
Watching you struggle with heavy builds. Trying not to let them fall of your work bench, I started to wonder when are you going to make a work bench you can lower to the ground, and lift up to working height? In Ivan Miranda style.
That’s a great idea indeed!
For the projects you make Ivan that's a fantastic idea since its a struggle sometimes too get the projects off your table lol love the go kart
A half plastic brake rotor....this should be fun :D
Well done
I get the feeling that one of your future projects will be a small scissor lift (made with 3D printed parts of course). :D
In fact, you may be able to build one with Miranda blocks come to think of it. hehehe
You're absolutely amazing, that's some true next level 3D printed project, maybe not adapted to 3D printing though but lol, if we can, why not...
I really like the suspension geometry. The car feels really agile.
Hey Ivan, loving this series as you are pushing people's perception of what 3d printing is capable of. Could I recommend Castle Nuts and Cotter Pins for the wheels, it made me nervous watching that wheel nut fall off.
Damn! even the lego f1kart has porpoising lol
You sir are a genius.
At this point, I am just waiting for Ivan to 3D print benchy in real life yacht-size and attach some V12 motors on it and go sailing away :D
Just A.W.E.S.O.M.E !!!
No! You are awesome! 👊👊👊
"Matt, I'm coming for you! Slowly... and when I get to you, I won't be able to stop."
That looks awesome, Ivan! I'm very interested to see how you're going to fix the braking. There's no room on that front end for any brakes! I'm really surprised how well the chassis held up, but considering it probably weighs as much as/more than you, maybe it shouldn't be surprising :D
Epic build!
TPU treads?!
Tires are made from Polymaker’s Polyflex
@@ivanmirandawastaken ah, my mistake.
Tread pattern might still help though.
Eres un crack!!
Gracias!!👊👊👊
Cotter pin....yer welcome. Hahaha. Awesome build!
what a smart man
Love the music already (I'm just at the start)
I like that your ads are often for products that we need as 3D printer aficionados. I find your ads as useful as your video.
Instead of welding use locktight 660. It’s amazing for this type of application and we use it at a sawmill to fix bearing in place and it can take one hell of a beating.
The second I started the video and heard the blood dragon sound track I knew this was going to be good
Parts without music are awesome :)
Your video editing is amazing
You might give the axel components some adjustment for camber and toe to help with tracking and cornering. But that will necessitate special parts and a more difficult setup. This project looks like super fun as is! I love the build video. It assembles so nice!
Did you do that "hit up you won a prize" thing? Seems phishy....
@@xander7462 Those things are phishy for sure. Zack at JerryRigEverything exposed how those scams work about a month ago.
Maybe use TPU for the tires, they should give more grip (also... print a grip on them) .... might work if you just print a TPU grip strip and glue around the tire
50 years ago it was a lawn mower engine and some waste lumber. Congratulations on reaching another goal! Now some cotter pins?
Que grande.... !!!! 👏👏👏 Un saludo desde Alemania.
I'm just gonna call it... and I mean this in the nicest possible way... Matt Denton doesn't stand a chance. 👍
amazing as always
You are far too talented😀😀
You should use cotter pins for the wheel nuts ;) Nice build!
You are an inspiration brother thank you for being you
👊
Vaya crack. Enhorabuena Iván xq todo lo que haces es espectacular
Saludos
😳WHAT HAPPENED AT THE END?!? Did the mill catch on the part?
Fantastic kart - I can't wait to see you race Matt! 😊
ironically, i think the 3d printed tires is what keeps the car together. lack of traction keeps the forces low :-)
As Stefan at CNC Kitchen has proved it's viable, I think you could create a good print recycling machine, one which lets you turn failed prints back into filament. You'd probably really benefit from it and might even push the technology forward a bit.
Cool looks fun 😊get your self a crash helmet? And up the voltage
I am here so early, Ivan is only on his third revision of the design.
3d printed parts are amazing. At the same time, I'm eager to see a 3d printed part that is lighter and last longer than other production methods. I 100% expect these "look at what I printed" parts to blow up after several uses 100% of the time.
nice Ivan ! also loving the music theme!
Amazing stuff, but I would get rid of the brake calipers and just use the motors to brake; it would drop some of the extra weight plus that way you can have regenerative braking to recharge your batteries.
Brilliant!!!!!!
Las placas de aluminio interfieren con motores electricos a pesar de no ser metal magnetico. Es bueno dejar un poco de distancia de la placa a las bobinas. Saludos de Mexico.
Just too freaking awesome! Love it!
I noticed the wheel locks all twist in the same direction. cars that have a single wheel lock have them tighten in the opposite direction that the wheel rotates so they lock is not loosened, you should try that.
They don’t. Right side nuts are righty tighty and the left side lefty tighty. I’m sure I neglected to tight that one at some point 🙃
can you wrap the wheel in some kind of rubber to give them grip? You are an amazing and inspirational guy. love your channel.
Locking pins for the wheels?
concerned that the brakes will easily melt the plastic. they get very hot. Also love your content as always.
I added nylon washers between the disks and the 3D printed parts because I feared the same (I can add an aluminium bracket if that happens) but there's so little grip when braking that I bet that the brakes cannot remove enough energy to get that hot. Thanks!!!
I'm not worried about melting, I'm worried the first time he smashes the brakes, they will break!
@@ivanmirandawastaken if you can add larger calipers or increase the surface area it would help. My father made a go kart for me when I was younger and he just had a bar that would pull down onto the tires to add friction. It's not the best solution but it would brake better.
Loving this video 😎😎😎
I'm really looking forward to seeing you race this thing. Incredible work and so much fun!
so fun !
i would suggest making the wheels out of a soft filament for better grip
Magnificent.
Wheel nuts on left hand side need to be left hand thread so they don't come undone....or you could just put a key, split pin or grub screw to stop rotation
change the thread direction for the right hand side wheel nuts as they are essentially undoing themselves when you drive.
Wouldn’t that make them undo themselves? (Left ones are reversed)
@@ivanmirandawastaken Basicaly you want the direction of rotation on a single axel wheel nut to rotate into the direction of the thread to make them self tightening (I think I am explaining that correctly)
I owned an old MGA with wire wheels many years ago and right hand side had a clockwise thread to tighten and left side were anticlockwise. this stopped the wheels from coming off because rotational forces kept the lug nut constantly tightened
That’s exactly what I did 🙃
Que trabajo tan interesante. Que inglés tan gracioso
Why not use a hall sensor for steering angle, then you can adjust rear motor speeds like an electronic differential, added cornering speed advantage and will help the understeer!
3:05 interesting ASMR segment :P
(no really - it was actually intesting)
(like a rare behind-the-scenes moment)
Brakes work by converting kinetic energy into heat through friction. But that heat must be dissipated. By getting rid of the metal hub, you lost quit a lot of heat sink and heat transfer surface, which probably made them less effective at dissipating that heat which is generated.
I barely touched the brake as it has regenerative braking. The brakes themselves are more than good enough but the wheels have almost no grip even though they are made out of TPU 😉
Did you put reverse nuts on the wheels
Yes although that would have done nothing for the one that got lose as it was the right hand side
You could just print huge lego technic parts and build official sets with them. One of those larger sets would look insane
more traction from the wheel?
Super cool. Very impressed at how not only how well the PLA PRO tires held up on the asphalt but also how they totally ate that screw like it was nothing.
As you seem to have more torque then can be put down, your motors could probably handle a larger diameter wheel on the back
Can you add a reverse switch so you can backup?
Wont the brake disk get hot and melt the plastic. Probably should be aluminum?
Might need to use a reverse screw for the right side axle. It's getting spun off.
Left hand side nuts are reversed. The one that came lose was the right one. I must have forgotten to tighten it. It got loose on the first turn.
Dude, you are so amazing! I love how you are able to build this and make everything work
considering you have a plenty big enough printer and enough experience maybe you should try printing some tpu tires to go with the wheels for improved traction ... unless you actually wanted a drift car
The tires are tpu.
so an idea tread on the tires might make it more stable.
Front brakes are much more effective.
wouldn't the wheels last longer and have more grip if you made them out of some sort of TPU?
Just like axles on cars, drill a hole through the nut/axle for a pin of some type to keep it from getting loose. Extend front wheel axles to make same width as back and add brakes. May also help wheels not rub on other parts. May need to adjust gearing for more torque.
Fighissimo! Che motori e batterie hai utilizzato per farlo muovere?
me: why isn't this popular?
also me: *refreshes to see it go from 200 views to 1000 in 4 minutes*
get some bigger pulleys for the motors, raise the voltage as much as you can, and get sensored motors (if yours aren't) and a vest, so you can enable FOC so you will gain torque at low speed, the tires should be made out of ninja flex so they are grippier, and ad some patter on them for the same purpose
I think one of the biggest things to try would be a spintend 100v100a dual vesc, theyre actually pretty cheap sometimes and a high voltage battery pack to suit (20s runs quite well on this platform), you'll have the power you need to smoke denton for sure!
Just how does the bracket where the brake disc is mounted not going to melt away?
Isn’t there a rubber material that can be 3D printed to the wheels?
How long was the print? What did you print it on??
You could coat the tires in some Plasti Dip. Supper cheap and should give you great grip.
That action camera dragging on the ground breaks my heart as a camera op. 😬 Also, should you trybsome softer filament to have better grip, maybe like a outer layer that you can swap after it is too used?
If you make the nut on the side that keep coming off reverse thread it will stop it coming undone 🤙
maybe a 3d printed hoist to get thing on and off of the work table.
Nice
I foresee those brakes not lasting very long when they do work. The heat generated in the disc is going to melt the plastic holding them on. (Was thinking that the first minute of the video)
Ivan, can you share some of the print settings for those huges parts? Whats your line width and layer high, and what do you use to extrude so much plastic?
