Modjul - Pop! Trucks and wheels

thingiverse

This design is built around being strong enough and light enough to withstand performing tricks. I spent a lot of time testing different designs, filament and print settings until I found the right combination that made it strong enough. This replaces the reverse kingpin trucks from the original modjul system because it's stronger, lighter, simpler and maintains better wheel alignment. Check out my results of materials and settings testing here with cool charts! https://docs.google.com/spreadsheets/d/1kNHv5hwBYRdDyKdxN3DF4e-Sy2Rp3Bn7hhZmjKep5r0/edit?usp=sharing To build this, you'll also need: * 6802 bearings (x8) 15mm x 24mm x 5mm (I paid $10 for 10) * A skateboard deck * Bolts and nuts to attach the deck to the trucks (x8) #10, 1-1/2" long * Kingpin bolts: 3/8" x 2-1/2" (x2) * Optional: 3/8" stop nuts To keep things simple, I recommend printing most parts in PLA Pro / PLA+. I've been using eSun's version and it's very good. It has high tensile strength, excellent shatter resistance, excellent layer adhesion, and doesn't need to be dried to print well. PETG can also work as an alternative to PLA+, although it has more flexibility. Just make sure to dry your PETG thoroughly and print it hot. I print at 252 C with a volcano block. If it's not completely dry, it won't print hot enough and won't get good layer adhesion. You'll also need a TPU for wheels and bushings, 85-95A. In my experience, 85a rolls faster. I've included large and small wheels. The small wheels don't roll as well, but they're better suited for tricks of course. See the original system in action here: https://www.thingiverse.com/thing:3426407 I print with the same extrusion width as the nozzle diameter. This is supposedly the strongest way to print, based on some testing done by others.
