Axle Length vs Axle Stopper

[Max Martin Richter]

I just pointed to existing prims that have the form, we could merge this with a 19 or 19.5 LDU long prim that represents the end of an axl (like Max suggested)

The seperator we have in 6538b is .5 LDU wide

Here's a picture adding the endcaps scaled at x=75%

I just made a measurement for 6538b. Total part length: 15.95 mm.
Insert length per one side: 7.8 mm. Which means, that with an idealized part length of 16 mm the stopper is 0.4 mm thick in total.
I have not checked how many parts are using the axle prim. But at least the plain axles could be changed quickly to a design using 3 prims. And parts with an 1L axle stub could be done as well, if we decide to make a 19 or 19.5 LDU prim with beveled end on one an open end on the other side.

Are we sure, that there is a special design for the stopper ring? I can cut on joiner, if we want do see this exactly. I cut an 6538b into a quarter. It is just a plain ring without any beveled  edges or anything else.
