About this 3D model

Trawling Tthingiverse I could not find a ready-made solution that fit my wide spools (155 mm wide). Also I have such a variety of widths that I did not want to print an exclusive (parametric) one for each width. This set is adjustable (30 mm - 180 mm) and only comprises of two distinct models (printed 4 times each). The flanges on the bearings are rounded to correct the "seat" of any slightly deformed spools.
