0.1 handless slim

To mount:

4x M3x12 (8 for both sides)
3x M3 Nut (6 for both sides)
Print two of the file that fits your side panel thickness

2.5mm
3mm
You will have to add 3 nuts to the top extrusions as the handle replaces the top panel clip and requires 4 nuts (3 new + 1 old from panel clip)

Remove the middle clip on the top extrusions but keep the nut in place.
Unscrew both screws that hold the top right and left extrusions in place.
Lift the extrusions just enough to be able to add 3 nuts in the outward channels.
Seat the extrusions back into place and tighten the screws holding them in place.
Reuse the existing nut (old panel clip) and the 3 new nuts to attach handle.
