Eryone Tinker SE PSU extrusion mount

WARNING

You will be working with high voltage electronics which may kill you if you don't know what you are doing!

Description

Took the stl for the Thinker (non SE) PSU bottom piece and worked from that:

• added a cutout to fit the switch found in the Thinker SE PSU
• adapted heights 
• added screw holes for mounting it to the extrusions

BOM

• 4 M4x8 bolts (preferably BHCS but SHCS worked fine for me as well) 
• 4 M4 2020 t-slot nuts (either the ones with the little ball bearing or the rotating ones, first type is suggested)

PRINTING

part isn't designed with shrinkage in mind, print it either in PLA or scale it and print it in ABS

ASSEMBLY

you will need to disassemble the bottom part of the PSU to swap parts, make sure you know what you are doing. Take pictures while disassembling the psu to make things easier later

The two screws that attach the PSU to the printed part, on the side towards the front of the printer, will be a tight fit. Make sure to raise the printer gantry before starting to have clearance for later

1. remove the 4 bolts attached to the original orange plastic cover
2. remove the two screws of the power inlet
3. detach the cables from the on/off switch
4. extract the power inlet from its slot and detach the red and blue wires (no need to remove the black one as it's already detached on the other end)
5. detach the 4 VCC and GND wires from the PSU
6. remove the on/off switch, ac inlet, and 24V wires

Now you will mount the new piece, attach it to the extrusions first and fit components later

1. insert the 4 m4 bolts in the bottom of the new printed part, and attach it to the back extrusions using the 4 m4 nuts. The PSU will hang a bit off to the side since making it flush would have it collide with the bed. The back of the PSU will be flush with the back 2020 extrusion
2. once attached reassemble all the PSU components in inverse order

you are done!
