These magnetic pipe clamps are based off a design by the incredible "Onwrikbaar". They can be used to clamp wrist shaped pipes
I strongly recommend using the included fusion 360 file to resize the pipe clamps to your own wris...pipe, as they are very small currently. There are parameters to change in the file. It's very easy but if your unsure I've made a video walking you through the process.
I built these to house the following magnet
I recommend that you use stainless steel bolts so they do not rust.
For the cuff hinge you need 1 M4x45 caphead bolt and 1 M4 nut
to attach the magnet you can use the screws that arrived in the kit and 4 M3 nuts. Or pass the magnet screws right out the bottom to screw it onto the right angle bracket that came with the kit. To hold the solid metal plate (strike plate?) you will need an M6x25 (i think, although longer won't hurt) bolt and nut.
I would suggest printing a test with just one perimeter and kill it after 10mm or so just to double check the size before commiting to a full print
If you end up making these I would love to see pictures!
3 perimeters to make it strong
