So this is a little 3D printing project (that maybe exists elsewhere, i don’t know), that I made in order to be able to maintain small and large pieces above a surface that is not specially made for tinkering (kitchen table and the like). This will allow you to cut or pierce « safely ».
It comes in two separate pieces: the main body and the holding part. The main body is 100mm x 100mm x 75mm.
I haven’t tested it yet, and you’ll probably have to print more than one to properly hold something (depends on how large the thing you want to hold is). To mound it you’ll also need a bolt and a winged nut. Put the bolt into the hole in the main body, with the head inside, heat it a little (not really needed but helps holding the bolt and the holder together) and put the second part on it, then just put the winged nut on top, you’ll use it to tighten the pieces you want to hold.
