Paper Towel Roll Adapter
thingiverse
Receintly, my local wally club enlarged the tube in their store brand paper towels so that my kitchen towel dispenser would no longer fit. The new center tube was 14mm larger in it's interior diameter so I printed up these adapters to keep the ends from being eaten by my holder so they could spin freely. This adapts the inner diameter to the new 48mm size from the old 34mm size. Print 2, one for each end of the roll and slide them in and they will snug up to a 35mm guide ring on the roll holder. I printed this in red pla on my HE3D K200 printer with no infill and .2mm layer height and .8mm wall thickness. This was created on OpenSCAD
