Flexible coupling with silicon tube

thingiverse

I Tried printing a few different rigid couplers, but the Z wobble was too much to handle. Then it hit me - using silicon tubing as a flexible joint between the rod and motor shaft might just do the trick. I spent some quality time with OpenSCAD creating parts that would adapt 5mm motor shaft to fit perfectly inside the 10mm tube's inner diameter, plus clamps to secure everything in place. It works amazingly well. I've got some Filaflex lying around and thought about making a flex tube out of it, maybe someday I'll give it a shot. For now, my current model is designed for 13/10mm tubes and a 5mm motor shaft, with a 10mm threaded rod. Print Settings: Printer: FrankenCube Rafts: Doesn't Matter Supports: No Resolution: 0.2mm Infill: 15% Notes: I used three perimeters with a 0.6mm nozzle, and it probably works just as well with less.
