This is a remix of a remix. I rised the foot at about 48mm high (45mm the foot + 3mm the base) in order to have space for more cooling case for MCU and PSU. You can scale the foot only on Z in slicer based on your needs.

Print Instruction:

• Foot_PLA.stl - PLA or PETG, 4 perimeters, 20% infill gyroid, 0.2mm layer high or more, 5 layers top and bottom, print as it is (upside down) without supports
• Base_TPU.stl - TPU 100% infill

BOM - for one foot

• 2 x M4x16mm Hex Socket Head Screws
• 2 x M4 t-nuts
• 2 x M4 washer

If you want 4 feet you will need 8 screws, 8 t-nuts, 8 washer. But you could use more feet if you wish.
