Cabinet feet

This is my first project. Please take it easy.
I decided to make these feet for my closet. I bought them online and they came without them.

I did it quickly and roughly in order to assemble the furniture straight away.
The suggested printing information was what I used to print faster.
You can try other settings if necessary.

I used 2 screws on each support measuring 40mm by 3mm internal thread and 4mm thread.
The internal holes of the support are 3mm for tightening.
The screw head recess is 8mm. You can use another similar screw if you want.
The space that enters the furniture is 12mm.
The height from the ground will be 50mm.
The total support is 42x40x70mm
