Axle Length vs Axle Stopper

[Gerald Lasser]

One problem is that the rounding is not scalable, so we need a scalable axle body primitive AND a non-scalable rounded end, introducing some more complexity/vertices. That said, I find too that some simple bevel would greatly improve axle look...

There is an axlecap primitive which looks like the beveled end



I also like the proposal of max

Whats about making a 19 LDU (or whatever is the correct length) primitive with rounded end on one side and another scalable 1 LDU long primitive without ends?
