3doodler grip w/ magnet boss
thingiverse
This will mount to the two #4 machine screw holes near the hot end of the pen. It has a boss inset to glue in a neo- magnet @ .333 (1/4") x .126 (3/16"). You'll just need the screws and magnet if you choose to use it. I used PLA at 205/ 90 w/ .3 infill and two perimeter shells.
