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

I've put it on the back burner for the time being as I finish some other projects. I'm nearly done with the next generation of my trains and an accompanying variant of it. When they are done I plan on starting to build it!

Thank you! I actually had considered something like this but for elements tricker to build with knex. I also thought possibly doing mechanical parts like a transfer table with this design while keeping the rest Knex would be useful too. If there's enough interest I can try to put something together!

That's awesome! I got my kits from local garage sales. However, they're also sold on reselling websites for decent prices. Happy building!

A maker's license of Solidwoks

also how did you make the rail and train?@@ModeledCoasters

The next version of my trains are being designed so I can print and sell a couple batches if there's interest. I'm nearly done with them so stay tuned for the next couple weeks for an update!

This set I do not. I'm currently working on a new and improved design that I could sell if there's interest. I'm hopeful to show it off in a couple weeks!

I haven't, but it's something I'll consider for the future! I'm not as familiar with blender as I am with Solidwoks, but I'll give it a try for the next coaster

I'm using a makers license of the software and paid $100 for a year subscription. I only recommend using it if you have prior experience using Solidwoks as the makers edition is extremely buggy.

I'm using a 1/4" OD polyethylene tubing I purchased from the Home Depot. Lowe's and Menards also sell it. This works with both my custom trains and the screaming serpent trains. You can also purchase it for cheaper with more options from an online store such as McMaster-Carr, but they charge a lot for shipping.

You could also use the black garden tubing that doesn’t need to be drinking water safe.

It's a 1/4" OD polyethylene tubing from the hardware store. I purchased it from Home Depot, but it is also available at Lowe's. The inner diameter is larger than the ID of K'nex tubing, so it's not perfectly compatible with the cross ties.

Thank you! I'm super excited to go beyond this and add even more to the coaster!

Thank you! I'm really glad my niche hobby can bring you and others some entertainment! I fully realize the audio isn't fantastic and it's defiantly something I'm going to work on for future videos. Thanks for the feedback!

Why not if it’s safe?

I'm sure that mistake must have hurt. Between my two mistakes I lost nearly a week of printing time.

I've definitely gone through in my head how I could make the cars take an even tighter turn. But realistically I'm satisfied with the turning radius for now because it's fairly realistic scaled up. The idea I've been playing with is shorting the cars to a single row with that row riding on the axle similar to how B&M builds their trains. I've begun redesigning my trains with that idea in mind. My current trains are very similar to the RMC trains with a ball joint at the center. I think the new version will be designed so that I could do either a style similar to B&M or RMC. I'm a little hesitant to go with the b&M design because it would double the amount of bearings I need making it far heavier. My track could definitely handle the weight, but I can't say the same for the knex track!

Those are definitely neat ideas I've definitely had. Once I'm more confident with designing and manufacturing the track I'm very interested in doing a Popsicle stick/printed hybrid coaster!

he hearted your comment uh oh what is he planning

This particular set of trains have a pretty annoying design flaw I'm going to go over a little in my next video. Therefore I'm not planning on making them available. The next generation will fix this issue and I plan on having those available probably by the end of the year. In the meantime if you have any questions I'd be glad to help!

The track was procured from a couple K'Nex kits. Two screamin serpent models and one thunderbolt strike kit. I try to use as many cross ties as possible to keep the track rigid. In my next video I'll be sharing how I 3D print my own track and giving some details on how to do it!
