Summary This is a dust boot for a 57mm spindle, its OpenScad so you can edit it to make it work for your setup if needed. The idea is that the brush can be easily removed if needed. I got the brush from a Miele vacuum cleaner attachment. This is a simple item and I have not commented or made the code parametric. Print Settings Printer Brand: RepRap Printer: TS3D Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.25 Infill: 50% Notes: Print settings done really matter you should choose what works best for your setup. Likewise material I personally like Esun PLA+ though my part in this case is printed in PTEG for no good reason other than it was in the printer.
