Dremel mount for my Printrbot 1405 Upgrade

For now it is just a model, an interesting idea for use my printer like an CNC for PCBs

IMPORTANT: This piece is under construction, use it at your own risk :)

Update 14/01/2015
Remodeled all pieces for a better performance, the past design have some issues not easy to fix

The now design is dremel_mount_v2_p1 and d_mount_v2_p2
