Printed at 0.20mm instead of 0.16mm, came out excellent. Still have to sand it and perhaps put some hockey grip tape on the handles. I hope it holds up well to abuse on the Nordschleife!
P.S. will chime in on how durable it is after a few weeks of use, but at 15% gyroid infill the overall structure, once screwed together, feels good. Hopefully the author can also let us know how well the wheel has held up for him so far?
