Customizeable Sliding Barn Door Replacement Wheel

A customizeable sliding barn door roller wheel that can be printed with a reasonably strong material like PETG or PLA+ with at least 80% infill. ASA would be even better, but PETG has held up great for me. I recommend including some slim tree supports. 

It is a perfect recreation of the original wheels. I was skeptical but they have worked perfectly to replace worn wheels on a very heavy sliding barn door mounted on a thin rail.
