Bike Trailer Hub Cap Cover

thingiverse

I bought a bicycle trailer with 16 or 20 inch wheels. The rubber hub caps were missing, so I designed my own. These friction fit. Unlike the original ones, they don't have a flexible dome, so you have to remove the cap in order to release the wheels - that's not a problem for me.I printed in regular TPU - you probably need to use a flexible filament of some kind.Sizing: I don't know if the wheel hubs are standard size. The measured internal diameter of the hub was about 28.4mm (which I guess was originally 1-1/8 inch) I think you should be able to scale these if your hubs are larger or smaller.
