Magnetic Screw Drivers

3 types of Magnetic Screw Drivers. Each screwdriver has a internal hole for sized for a 8mm magnet. A Tall skinny one, a skinny to big V and a short chubby one. There are two versions of each. First version holds one magnet, the “2mag” version holds two magnets. The 2mag / two magnet version holds onto the bits significantly more.

UPDATE - added a new version of the V model that is a little taller. 
UPDATE - I purchased new magnets and discovered my old magnets were very thin, about 1.75mm. So I uploaded new models named "2mm" for magnets that are 1.95mm.
