The original four casters on my ShopVac rolling base were low quality and one of mine had broken after “light” use. I had a set of five office chair casters left over from upgrading my original office chair casters to premium roller-skate-style rubber casters (because I don't like rolling to the edge of an office chair mat, have hardfloors, and don't want to scratch my floors - LVP), but the new caster post diameters did not match the ShopVac's. So I made an adapter. This works for ShopVac model CH87-650C or equivalent. For this model, I printed two (2) parts per the model, then printed two (2) mirrored parts.
Original Caster post diameter 7.4mm
Premium caster post diameter 11mm
Printed with PETG
0.4mm layer height
0.6mm line width
Infill 50% Concentric
