I made a mount for my brothers racing simulator triple-screen setup, for the external monitor PSU's of his ASUS ROG 32" screens.
The PSU's are dimension 76*29,5mm (max) each. Mounts to your T-slot using M8 (max) screws and T-nuts.
Print in PETG with many perimeters/high infill for rigidness over time, as PSU's might get hot and deform PLA.
The author marked this model as their own original creation.
