I might have dropped my electric radiator and broken a plastic castor mount/foot.
When I printed it on its side the piece sorta split as I inserted the castor/wheel. So maybe 100% infill is the way to go. Possibly printing at a skewed angle so that filament rings would surround the castor spike as well as the snap-grip. Either might've prevented the split. Still, the split seems to be only a minor cosmetic problem.
