YEET

Ignore print settings listed by default; resin only.

To use the .stl's, see below. But the scad's the thing.
It lets you:
produce caps w/ arbitrary sizes between choc-minimum through larger-than-mx standard;
lets you make 1u+ caps of arbitrary length;
choc or mx legs;
mx skirting or nah;
convex or concave, with adjustable front falloff
arbitrary sloping on sides / front / back
lets you produce an entire column at once, with adjusted tilts for each
Lets you make a proper r3 w/ front and back falloff (automatic when tilt is set to zero)
etc, etc.

How to:

Open 3d modeler of choice, one able to import stl's. Meshmixer is free and can do everything required.

Select a base; choc-spaced or MX-spaced.

Select a stem; choc or MX. Rotate it 90 degrees if desired. Apply it to the cross-shaped hole in the base, so it fills the hole.

Select an indicator; apply it to the rectangular opening on the base.

Select a top. This, you'll need to resize so it matches the base.
