I'd like to build a Top Thrill Dragster or Kingda Ka as my next project. I know others have built both before, but I'd like to build one with an air launch. I started working on it last May, but got busy with unrelated events. It'll probably be TTD because I don't think I have the ceiling height to build Kingda Ka. I'm going to get back to that when the Demon Drop project is over!

Thank you! Some of the mechanisms are replicated from the real ride, but most are original. I've got no prior knowledge about the ride other than what's available on the internet. I'm an engineer so it's not too far off what I do professionally.

@ that’s cool! I want to pursue a career in engineering!

I love my mk4s. It does have a couple of quirks, but overall it's been a super reliable workhorse that I can depend on. It's a night and day comparison to my old ender 3s. The core one is super tempting and I'll probably buy one as a second printer.

My next project will be an air launched knex/printed coaster! Knex projects are faster, but I enjoy 3D printing projects too.

@ModeledCoasters yh I'd love to 3d print more for my builds but it takes sooo long 😂

I totally understand, but I've gotten better at it! It only took two months to design the demon drop model. Printing it only took a couple weeks. The holidays have slowed construction down. I design 3D printed parts nearly every day for my job so I've gotten pretty fast at it. If you need some help just let me know!

@ModeledCoasters definitely worth giving you shout outs in videos and links in my descriptions in return for trains designed 😂

I can probably help you with that. My email is modeledcoasters@gmail.com if you want to talk more.

Thank you!

Thank you! These are 10x5x4 mm ball bearings that I believe are intended for RC cars. They come with a rubber shield and are packed with grease. I've removed their shields and the grease to decrease their resistance. I purchased them from Amazon, but they are also available from RC car websites or AliExpress.

@ awesome! Thanks for the quick response! I’m looking at making my own 3d printed model coaster soon, and was trying to find some bearings for the bogies that will be appropriate lol. I’m going to be using PFTE tubing as the “track” and will be 3d printing some track spines for it. Anyways, cool project and keep up the good work!

That's awesome and I'd love to see a video of it finished! I'm considering making one too as my next side project. I totally understand the struggles of balancing school, hobbies, and life. It makes completing these projects even more satisfying.

@ there will definitely be a video and I can’t wait to see more of your projects!

Thank you!

I will not be sharing files simply because there's way too many and I don't have the time to make instructions. Also many parts are too big to fit on standard hobby printers. I'm a mechanical engineer for my day job. I use a similar set of skills when I design parts for work, so that helped me complete the designs as fast as I did. It took two months to do the design work. I can practically design 3D printed parts and machines in my sleep.

Thank you! That's a coaster I built a few months ago to test some custom trains for it. I never finished it because I got busy with other projects, but I like keeping it up.

@ModeledCoasters sick I would love to try making a fully 3d printed coaster but my skills are no were near this level I'm going to stick to knex for now but in the future the collage I'm going to offers a 3d printing coarse and I might have to take it.

@@knexrecreations6875I did MODEL a fully 3d printed SS train compatible coaster, but only printed a 3rd of it and then took it apart.

These are cheap linear solenoids. I used them because they were cheap and easy, but when I redo this project in the future I'm going to use a different system.

Actually, it is my 3d printed rollercoaster model using K’nex SS trains and tubing. It’s just two turns and a corkscrew right now.

Both are super cool! Do you have a video of the pipe organ working anywhere? I'd love to see it

I also am "meh" with normal drop towers, but the old freefall rides always intrigued me. I'm super excited to share more!

Thank you!

My email is Modelecoasters@gmail.com. Feel free to reach out and I'll try my best to help!

Thank you! I'm really happy that other people are enjoying them and I'm working hard to get some more out! I've gotten a lot of requests to do both and I'd love to get to them eventually. I'm working on an air launch for a k'nex coaster. I could make winged trains for it while I'm at it!

Thank you! I have a second one that was printed in red filament. I hope to use both in my next project that I'm working on

@@ModeledCoasters also really looking forward to the pneumatic launch would you add the retractable brake fins like on maxx force ?

I watched the video scratch that

That's super cool and I look forward to seeing it! Designing trains is surprisingly complicated. I highly suggest checking out both my original video of my train design and the recent update video of them. By far my biggest suggestion is to create a design that is forgiving of track imperfections, but not too forgiving. If the parts are too loose or allow for too much movement then it makes them perform poorly. A good 3D printer and quality material for it is extremely important. Finally, the size of the model will have some impact on the complexity. If the scale is too small then creating and printing functional parts becomes more tricky. This is why I haven't done any projects with micro knex.

@@ModeledCoasters thank you for the advice

The truss supports are the quickest way to build a structure. I would keep an eye out for my next project. No spoilers, but I plan on using custom supports for it!

Maybe someday I'll have the space and money to do that! My best tip is to give your designs some "wiggle room." The printing process is never 100% accurate to the computer designs, so building in some adjustability saves you a ton of time and materials. This was something I learned the hard way pretty early into the process. Also use quality materials and glues. The super glue I was using didn't hold up very well and that doomed the project.

I'm actually hopeful to build a LSM launch someday in the future. These trains sit higher off the track. With the added height I've been able to squeeze some magnets underneath for roll back brakes on my air launch project. I'd like to try to use the magnets for a LSM launch at some point in the future.

I'm super excited to start sharing the progress! It's been a project I've been wanting to do for a while

That's super cool! I personally modeled mine to look similar to TT2's trains. I can't wait to see the final product!

I'm super excited to start sharing the progress for it. Its definitely going to be a huge time commitment, but it's also a project I've been wanting to do for a while!

Yes

I'm planning on selling a couple batches of my trains once I finish the next generation of them. The design is nearly finalized and I should hopefully be sharing more information by the end of February! I wasn't really intending to sell any track models as I don't have the capacity to make them. But if there's enough interest I can look into it.

@@ModeledCoasters Amazing! I’ll check back regularly for any updates. Thank you
