Modjul Skateboard System - Deck, Trucks & Wheels

Check out this video here: https://vimeo.com/316969498 The goal of this project is to create a fully functional skateboard that can be printed at home without needing special materials or printer modifications. And yes, it works perfectly! I am using a Volcano hot end for speed, but you don't need one - any hot end will do the trick. The main deck requires the full build volume of a 300x300x400 printer. There are a few parts that can't be printed: * Bearings for the wheels: get some high-quality 6903 bearings. * Bolts for the kingpins: you'll need to buy these separately. * Bolts, washers, and nuts for mounting the trucks and connecting the deck parts: check out the "Required Parts" section below for details. You can print the smaller parts (trucks and wheels) on a smaller printer and use a conventional wooden deck. Alternatively, you can print the deck and use conventional trucks and wheels. The trucks are reverse kingpin 50 degree, with a reversible hanger that's 140mm wide. The axle width is 214mm. This design is perfect for cruising, not tricks - which require stronger filament than the recommended PETG. I haven't tried printing any parts with Polycarbonate or Nylon, but feel free to experiment! When attaching the tail to the main deck, use a plastic bonding agent like Scigrip 16. Without it, there's too much stress on the bolt holes and they might fail. You don't need to bond the nose, as there's less strain on it. I've tried a few different TPUs on the wheels: Priline 98a, Sainsmart 95a, and eSun 85a. Check out the results here: https://docs.google.com/spreadsheets/d/1oognSRkHh37sHCIzwKX4GOkM-d9Iz_LIPP12pA2XyIk/edit#gid=0 If you try other TPUs, let me know what happens. I expect Ninjaflex will perform similarly to the eFlex. You can remix my design freely using Fusion 360 or any other CAD software - I've included the source files (.step and .iges) for your convenience. One more thing: skateboarding is super fun, but it's also pretty hazardous - so always wear a helmet!
