Keyway Peg/Slide for Tesa Micrometer

Replacement of missing keyway part from a Tesamaster micrometer with mechanical digit counter. Redesigned from cap90's "Brown & Sharpe Micrometer Part" in Fusion 360 and scaled for printing with Cura.
I extended the length of the keyway slide to assist in installing the part, but after many attempts I still managed to shear off one of the two pegs. The part seems to work as is, and the micrometer now functions correctly, so I won't modify it any further unless it breaks again. I printed this part in PLA, but would suggest considering a stronger material if possible.
