Does it work? Absolutely, it does! UPDATE 04/18/2019: I've shared better trucks here: https://www.thingiverse.com/thing:3573863 I strongly advise against using the older trucks as they are heavier and do not hold their alignment well. Additionally, these old axles can fail if your layer adhesion is less than perfect. I am utilizing a Volcano hot end for speed, but it is not necessary. The main part of the deck requires the full build volume of a 300x300x400 printer. There are a few parts that cannot be printed: - 6903 bearings for the wheels. - Bolts for the kingpins. - Bolts, washers and nuts for mounting the trucks and connecting the deck parts. See the "Required Parts" section below for details. It is possible to print the smaller parts (trucks and wheels) on a smaller printer and use a conventional wooden deck. It is also possible to print the deck and use conventional trucks and wheels. The trucks are reverse kingpin 50 degree. The hanger is reversible. Hanger width: 140mm. Axle width: 214mm. The intent of this design is for cruising, and not doing tricks which would require stronger filament than the recommended PETG. I haven't tried printing any of the parts with Polycarbonate, Nylon, etc., but I'm eager to hear if you decide to try it out! I highly recommend using a plastic bonding agent when attaching the tail (e.g Scigrip 16) as there is a lot of strain on the bolt holes without it. The nose is probably fine without being bonded as there is much less stress on it. I've tried several different TPUs on the wheels: Priline 98a, Sainsmart 95a and eSun 85a. See the results here: https://docs.google.com/spreadsheets/d/1oognSRkHh37sHCIzwKX4GOkM-d9Iz_LIPP12pA2XyIk/edit#gid=0 Please let me know if you try other TPUs and what your results are. I expect Ninjaflex will perform similarly to the eFlex. I've included my source files (Fusion 360) as well as .step and .iges so you can remix freely. Caveat: I'm not a skateboarder or an engineer. Skateboarding is extremely hazardous, especially when attempting tricks. Always wear a helmet. https://vimeo.com/316969498
