Allen Key Handle M3

thingiverse

This is a handle for an M3 allen key to have a better grip and make more torque. To print this you have to pause the print when it is about to close the slot fo the allen key, you can tell because there is a square on the top right corner of the slot for the last 2 layers or so. Put the allen key in and resume the print. If you want you can use the model version w/support to support the key so that is doesnt fall off the slot while printing.
