This is a mount/cover for a 30A PSU for the Anycubic Kossel linear plus. It has bolt holes for the extruder to sit on top, and works well with the back spool holder (https://www.thingiverse.com/thing:2872984). Most of the bolts are M4x10mm, but for mounting the power supply I used M4x8mm bolts so they wouldn't hit the PCB. I bought extra M4x10mm bolts (you need 10), and used the M4x8mm bolts that were in the kit.
There are spots to zip tie wires on both the top and bottom models, helpful if you're running the effector wires there like I did. To wire the power supply, you have to put the wires through the bottom mount and connect them, and then slide the bottom mount onto the power supply. If you are using the extruder mount, make sure to bolt that in before putting it on the power supply.
Note: this is for kossel printers that use linear rails only! Do not use this if your printer uses sliders that slide on the sides of the aluminum, because the top mount will interfere with them.
I've attached STEP/STP files for easier remixes.
