Parametric bushing

thingiverse

Parametric bushings were created in OpenSCAD for coupling filament spools with a spool holder. The model is fully parametric, allowing easy adjustment of bushing size and sturdiness for different usage scenarios or axis diameters. Smooth center holes work well with wooden dowels, enabling spools to move 2-3 turns after a gentle push. STLs are included for orbitech and bitsFromBytes spools. This module accepts height, radius, hole_r, border, recess, and num_support parameters. Print and enjoy!
