Hey everybody,
you don't necessarily need the magnets, but it's just nicer with them. I use simple 10x2mm round magnets which I got from amazon and glued them in with CA.
I uploaded a double version and a single one. Double version: the distance between both mounts fits for my size 46 shoes, so smaller sizes will not be problem.
The countersink is for 3mm screws.
I used standard PLA.
