Dual spool/reel rack/holder

Rack/holder for two filament spools/reels. Fits 1 kg spools of the width (ca. 8 cm) and diameter (up to ca. 19 cm) seen in the pictures.

The central hole diameter of commercially available spools varies: the thin rollers in the main design file are supposed to be used with cylindrical adapters for various spool central hole diameters. Two of these are supplied as the .STL and .SCAD files: these fit the spools that I have come across and been buying. No guarantee they will fit any others. Desi
