Deburring tool handle

A simple holder for 3.2mm deburring blades.

The handle is one piece. The tip is split by a small slot, so the blade can be pushed in and will snap in place. The ring keeps the two halves together.

Update dec 25:
Added new model files for the handle that have a slightly looser fit, in case the blade is not rotating well.
I also added XY scaled files of the rings,  so you don't have to adjust scale in the slicer.
--> I'd recommend to try the 0.2mm play version of the handle, and the +2% scaled ring first.
Let me know how it works!

Printing:

• The handle is printed flat, with support under the threaded section (see photo).
  The ring is printed standing up: concentric fill, top and bottom.
  I printed in PETG, 0.2 layer, 0.4 nozzle and 0.45 extrusion width (default PrusaSlicer setting 0.20mm quality)

• 3 perimeters wall, 20% cubic infill (2 perimeters and 15% seems to be strong enough too).

• If the fit of the tool or ring is not right, select one of the alternative files.

Assembly:

• The slot in the handle is only 0.2mm wide. Depending on the accuracy of your printer you may need a knife to open the slot up.

• The deburring blade should push in and snap into place. You may need to open the slot a bit (e.g. with your thumbnail or a screwdiver) to push the blade in and get the blade out again.

• Clean up the supports from the handle. The thread is pretty coarse and has some play, twist it on and off a few times until it runs smoothly. 

Any feedback or suggestion for improvement is welcome!
