The file 'Tape Dispenser Core – Scotch Heavy Duty No. C-23 3D Printer Model' is (stl) file type, size is 2.6KB.
UPDATE: I found after three weeks of use that the spindle broke unless it were printed 100% infill (solid). To save material I have clipped out the barrel, so that printing it solid wastes less material.
Scotch Tape Heavy Duty Core. If you have an old heavy tape dispenser that seems to have a 'larger than average' spindle/core width try my core.
Barrel = 25.0 mm
Spindle length = 42.4 mm
Spindle width = 5.5 mm
