Spool Spindle

thingiverse

This is a filament spool spindle designed to reduce the torque necessary to unspool filament while printing (on a Prusa i3 with 7mm threaded rod spool holder, or any other similar printer) -- give it a shot if you're having under-extrusion issues. The dimensions were based on Hatchbox spools, but you can easily scale to other dimensions. As designed, I printed two short pieces for each side of the filament spool. I also included one long solid spindle if you'd rather have a single piece. Print Settings Printer Brand: RepRap Printer: Prusa i3 Rafts: No Supports: No Resolution: 0.3mm Infill: 100 Notes: Prints without rafts or supports. I printed 100% infill for strength, but it's probably not necessary.
