Rack ends for DiYnderv2

These are little rack clamps that enable fittings to be attached to the v2 herringbone rack. The simple collar and the modified collar have square holes for K&S brass tubing to be inserted. The Collar 01 is the original collar for the rack, can be used as an end stop or with some wire. Use m3 allen cap socket bolts and nuts. I printed these in PLA at 100% infill with o.2 layers and a 0.4 nozzle
