OrbitalToast's Drafting Compass was almost perfect for my needs, namely being large enough to accommodate a Rotring 600, but the point wasn't precise enough for my needs, so I remixed it.
The metal point is a small nail with the head clipped off. I had to bore out the point hole slightly with a 1.5mm drill bit to get the nail to slide in, then dipped the non-pointed end in superglue before inserting.
I assembled the compass with M4 bolts with washers.
If I do a version 2 of this design, I want to perfect the hole so no drilling is required, and modify the bolt holes for metric hardware and a recess for washers where the parts interact.
