After a few days I can get back to you with some updates. I managed to create two parts from scratch – but they are still compatible with Nutz95 design. I have uploaded them to Thingiverse here. What feature I’m most proud of is designing part mount around aluminium extrusions. I have added 8 mm rectangular pins, fitting 30x30x8 mm aluminium extrusions row holes (which are actually 8,2 wide)
