Clean up sharp edges and brims with this handy deburring tool handle. Requires only one printed part and a small section of filament. The blade simply snaps into place without the need for buttons or hardware.

Print on end with a brim and no supports. Once complete, insert a length of 1.75mm filament into the larger of the two side holes until it is fully seated (about 10.5mm). Do not force the filament in too far as this may cause the filament to buckle and make blade insertion more difficult. Trim off the excess flush with the handle.

The small hole opposite of where the filament was inserted allows filament to be pushed out if it ever needs replacing. Simply push the filament back out with a small tool (tweezers work great for me).
