I bought some insulated screwdrivers from AliExpress (see link below) and I wanted a holder for them. I decided to make it magnetic.
The holder has a tapered circle to match the taper on the handle of the screwdriver so they fit in more snuggly than just a normal plate with holes in it.
The spaces for magnets are set up for 12x6mm magnets (12mm diameter and 6mm thickness round magnets). I used superglue to put them in and then covered them with some “Plast-aid” plastic resin/epoxy stuff to make sure they couldn't pull out.
I also added a groove where you can put rubber bands to give some extra friction in case you are having trouble with the holder sliding on smooth metal.
