Recently I bought a cheap deburring tool, unfortunately, the piece that held the blade broke (after two days) so I decided to create this handle as a replacement. 

The handle can be printed in PLA without supports and uses 3 m3x12 screws to secure the blade (you also have to put 3 m3 brass inserts in the holes at the top of the handle) 

The handle is made of two pieces with an inside space to carry a replacement blade or whatever you want.

the threads are acme T16x2 (millimeters)
