Small foot for pcb

Small foot for mounting pcbs.

The foot is roughly 1x1x1 cm. The top of the foot has an indentation with a radius.

I thought I made the mounting hole 4mm but I needed to drill the hole to accept the 4mm screws I had.

Pics show how the board is mounted in a tin (I suspect an old Belgian chocolates) box. Mine is printed in pla.
