I remixed the VzBot handle to match my front panels (135mm between holes). Not printed it yet, so be warned ;)
Because the screw holes align with the 3030 extrusions and I need the screw head to fit inside the extrusion nut, I used 2 flange-head M3 screws, 14mm long, and 2 M3 lock-nuts which are mounted outside. My panels are 4mm thick.
In the pictures, you see parts of my whole printer. Some of the parts are available elsewhere:
I'm not gonna ask for a coffee, but please make sure you give me a like if you find this model useful.
