3D Printed Propeller for 50 HP Tohatsu
HTML-код
- Опубликовано: 3 окт 2024
- I have been interested in developing a spare prop for my Tohatsu. This is a video of the first field test. The prop was 3D printed using High Temp PLA. I was able to achieve 2500 RPMs which is enough to get back to the boat ramp. Feel free to post any questions you have. Sorry about the orientation and audio but the video kind of speaks for the results
Awesome job man! I've an electric engine with 0.33 hp, so I plan to actually print fully capable replacement propellers at home! :)
Ordered the printer couple days ago.
Awesome!!! What kind of printer did you get?
@@markingle8980 FLSUN QQ-S.
Already printed me a Lenin, failed to print another one (tangled, learned how not to tangle again: ruclips.net/video/uf66_3bzIgc/видео.html ), and retrying the print. :)
How did this work out. I'm thinking of printing a weed killer prop. So adding some razor blades 🤣
as an emergency prop, this is awesome...
What material is that bro? I'm about to buy a 3D printer today! Thanks!
Edit: I read the description, good job!
Where can I download the cad files for this propeller? Cheers
this is crazy awesome, thx, i am gonna follow in your steps
Can you send a link or something with the file of the propeller ? I whould like to try to print it from PA-CF or PA-GF. Thanks!
It’s on thingiverse
You can toroidal propeller
very good for emergency prop....
thumbs up...
Print settings ?
How long you tasted it?
What PLA works long time underwater??
Which are better: PLA or PETG?
Creative Blue this was done using PLA+
Creative Blue this was printed to use as a spare.
Was it well balanced? Sounded like maybe not, but couldn't tell.
John Yager no more vibration than the aluminum prop. Max RPM was 2800
Did you personally CAD the internal spline or did you find a part file? I’m having a hard time doing the spline myself
No I didnt use a spline.....I created an inner coil along the exterior of the hub...then an outer coil that was longer with less curvature. The outer coil was set at the distance of - the tip of the blade to the edge of the exterior (hub). This gave me two paths to Surface Sweep. I then created a sketch looking down the Z axis. The sketch was the shape of the blade that I traced with a pencil with an aluminum prop sitting top of a piece of paper. I was able to keep the pencil vertical while tracing. Next I extruded the outer section of the sketch (not the blade shape) and performed a cut. This produced a very thin blade that I thicken to 6mm. Finally I did a circular pattern along the Z axis to create the other two blades. I would be happy to share the design but I stop using Fusion 360 because it got too expensive. I can send some screenshots if that will help.
I used the b series prop generator and made the spline myself. Not that hard, just draw an outer circle, an inner circle, then draw a trapezoid between them. Next, measure your top, and measure your bottom. Make sure you add some extra space so it'll fit. If you're not sure, just print a few layers, stop the print, and test fit. Adjust accordingly. I had to file down using some small files, but in the end it just fits. Excited to test it out this evening on a 10hp electric outboard.
Can you share the stl file or are you keeping your design closed source?
John McIntyre it’s on Thingiverse. But I need to recess the front to offset for the washer. Otherwise you cannot get the cotter pin in to lock the nut. Let me know if you want to print the prop and I’ll correct it.
I would definitely like to print the prop would you be able to provide the link on thingiverse or what to search under?
how big is the propeller ? 250mm 300mm diameter ?
Takis Vasilopoulos im not sure what the measurement is in mm but prop was modeled after a 11”x15” aluminum prop.
@@markingle8980 so it's more than 300mm how much power did you run through it ? That's a lot
I stopped at 2800 rpm and drove around for 10 minutes. It’s only purpose is an emergency prop
These have been shown to work best when printed with polycarbonate (PC). And coat them with a resin or epoxy (I used XTC-3D to waterproof and food safe my prints). It made mine at least 2x stronger against the sheering forces of the prop by coating it, and it took less than 2 mins.
Will Pla or petg coated with xtc-3d be strong enough?
Can you send to me the model?
Diego Di Giacomo do you mean the STL?
@@markingle8980 yes! I mean the .stl
Can you send to my email?
Diego Di Giacomo it’s on Thingiverse
@@markingle8980 i have looking for it but is not specific for my mercury 40, how you do?
Diego Di Giacomo how many spline? 13 or 15?
