BSB2020 EXTRUSION CABLE CLIP

I needed a twist and turn cable clips for my 2020 BSB type extrusions for BLV MOD printer.

This design works as drop lock nuts - idea is that is so snug that it stays in place well.

NOTE: The CLIP which is with piece of extrusion, can not be twisted in place, just slide it from the end of extrusion.

UPDATE: made the bottom more spherical, so it fits other kind of extrusions better (but not tested I have BSB 2020 type only)

UPDATE: Openbuilds V-SLOT is smaller than BSB slot, I will later design part that fits in it.
