These are OEM-style rear feet for the HP 8116A function generator.
I printed the hole caps in a flexible but the original HP caps are hard plastic. Your choice.
I recommend adding a modifier block to change the perimeters or infill to 100% around where the screws clamp down to provide strength.
I may create the feet for the bottom of the unit but I usually just stick rubber feet on there.
