This is a holder for a dremel when using a milling toolhead on the MakerBot TOM. I based this off of Pointedstick's design of the Ultimachine spool holder. This is to hold the dremel while it powers the cutting bit with the flexable shaft.Print it off, hang your dremel or dremel like knock off on there while you cut circuitboards with your MakerBot. This fits in one of the front square holes on the top of the machine. Remember to post pictures!
