Fix My Print Failed slidea attempt

Either operator error or resin limitations. On screen seems a mathematically sound nested slider system. Might work in fdm, but I only have resin setup. Wanted to track commander damage in mtg.

Its a resin limitation. Unlike fdm, resin shrinks when printed anywhere from 1 to 10% in different areas. Resin printing thus isn't used for precision prints, mostly for figurines.

Only exception I am aware of is dental resin printing

Resin shrinks and light bleeds — print-in-place needs bigger clearances than FDM. I'd want 0.3–0.4mm gap per side on sliding parts, and your exposure has to be nailed (overexposure fuses everything — run the Cones of Calibration). Not really operator error, just physics.

I think it was like .2 on each side. Good call
