Rim with center nut lock
A remix of the original rim, but with center lock nut.
I modified the spokes only, the rest of the dimensions are the same.
There are two rims, one with supports and one without.
I found that without supports under the spokes it was a bit difficult to print with ABS.
The one with supports has got hollow spokes, reduces the weight a bit.
The Screws are M2x10mm socket head bought on Ebay
I got these:
