So like many before me I've produced my own PSU Mount.
I wanted to mount on the lower table rear left leg but the wires aren't long enough to use the enclosure locator route. So I've cut into the base LACK and made a cable guide and cover.
The PSU mount uses a stainless bobbin I happened to have. With two screwed into the threaded holes pn the side of the PSU it's a slide on fit. The base support just makes it more sturdy. Two sliding fixings would work fine IMO. The stainless bobbin could be replaced with one made in PETG.
The cable guard cover strengthens the cutout, although I realised the table didn't need this once I had made the slot. However, It does keep the cables away from the perspex sides when replacing the upper enclosure.
The gCode files are for PETG and 0.2mm layer height.
All Parts print without supports.
