16mm Shock Bladder for Arrma 3s Big Bore Ebay Shocks

thingiverse

This is a custom bladder made from super flexible Ninjaflex TPU to fit Ebay Big Bore Shocks for the Arrma 3s vehicles. The standard Ebay Arrma 3s big bore shocks lack a bladder, so I designed one myself. While functional, I'm unsure if it will withstand long-term use, also due to using a 0.4mm standard nozzle I can only print the walls of the bladder that thin, resulting in a more firm bladder compared to a silicon bladder you could purchase. To install, simply insert into the shock cap, and you might need to use a hobby knife to push the edges down into place within the cap. So far, I've installed these with zero leakage issues. THIS IS A WORK IN PROGRESS, CURRENTLY TESTING THESE TO SEE HOW WELL THEY WORK AND WILL LAST. Printed using Ninjaflex 85A hardness TPU, 0.4mm nozzle, 0.12 layer height, 100% infill, printed flat side down with zero supports on a glass bed. I've included the gcode used to print this on my Ender 3 Pro and sliced with Cura 4.5 for others to use and/or tweak if desired. If you want to print this, remember you will need to use super flexible filament; don't bother with TPU above 85A hardness.
