Description
Holder for the black power supply unit (PSU) (Mk3s and maybe Mk4s). Uses existing metric holes for a stable fit.
I was not satisfied with the power supply holder solution from the IKEA Lack V2 https://www.printables.com/model/3673-prusa-enclosure-v2-mmu2s
because the PSU placement was only possible on one edge and the solution at all is not tight and stable enough.
My design supports mounting the PSU in all positions and directions, because it has a tight fit and supports to use existing M3 (with nuts) and M6 holes from the PSU to ensure the placement inside the holder.
Furthermore, there is no need for removing the cable cover for mounting and unmounting the PSU holder with wooden screws on the preferred position.
If you want to install it behind a wooden sheet / plexiglass/ acrylic sheet you can make a (U) cutout 45mm high and 50 mm wide and use my cover for smoothing the appearance. Just scale the cover roundabout 0,5 mm wider than the cutout for a tight snap in.
For printing I used PETG for the holder for better flexibility and PLA for the cover. I'm mostly printing with 0.6 nozzle and uploaded the profiles.
Would be great if you post some makes and feedback.
Happy printing!
