[Suggestion] Curve the npeghole primitives

[Magnus Forsberg]

All up to the 13 have one same element this topic was about fixing.

IMO that wrong. They are differently used, and designed. And should be different. Editing them all, would create a bad result

I will go through all the parts using those primitives, but for that I need primitives themselves to be on my hands

When I reshaped the axle holes I edited my own library and then used them coloured.
1.) edit the primitive, place it in your own unofficial p-folder.
2.) hard code the edited prim in a "weird" colour
3.) remove the corresponding official primitive.
4.) examine the result. I used LDFind and LDStructure a lot in my investigation.
