Dui, ni shuo de dui
That’s some cool whells, very nice project!
Just one suggestion: the inside part angle is pretty pointy. given the fact that the inside part is made of some stiff material, versus the outside part made of soft material, it is likely that, at some point, this pointy edge will cut through the tire, especially if you have some load.
Maybe you could change it to a bit more rounded edge profile., something like that (sorry for the horrible paint drawing):
Just a suggestion, maybe I’m wrong and maybe it won’t affect anything, only time and experience will tell you. Could worth a try though.
Again, very interesting stuff, I’ll follow your thread to see your progress.
Could you post pictures of the printed parts unassembled, and, if possible, during assembly?
