Adjustable width filament spool holder for 2.2 kg (and other) spools

thingiverse

The spool holder, designed for placement beside your 3D printer, is versatile enough to accommodate varying spool sizes. To achieve this, you may need to print a new central rod of the appropriate length. Aside from the plastic components (print file A twice and file B once), this project requires two 10x19x5mm ball bearings and four sets of screws/nuts/rings.
