This is a version that I did so I could use a 608 bearing and TPU tires.
I printed in PETG and the tires in TPU.
Print at 0.2mm.
Glue together body half's. The rest snaps, locks or press fits.
Note: axle-b has a bit bigger part where the 608 press on. Try this if the normal axle is loose.
The author remixed this model.
