I created this adapter for use with the following brand of relabelable keycaps from Aliexpress: https://www.aliexpress.com/item/1005003400000804.html

After buying the above caps, I realized that the two connector posts on the sides weren't meant to attach to stabilizers (instead they are used if you want to attach the keycap to two 1u keycaps, presumably for use in ortholinear POS keyboards).

I solved this by cutting and sanding away the existing posts in the keycap and gluing this print in their place.

The intent was to simultaneously match the total height of the glued keycaps with the similar 1u caps, but they still seem to be off the mark, either due to me being new to printing and screwing something up during slicing or printing, or I got some of the measurements wrong. I might revisit these at some later point and try to get the height on point.'

The picture shows the adapter glued in place, next to what the original looks like. Note the difference in spacing between the posts.
