Flat Keycap

Have you potentially made yourself a switch tester but thought “wow I don't want to buy all those keycaps for this” or maybe you printed a Keycappie but he needs a little hat. Whatever the purpose here's a keycap that dimensionally is suspiciously similar to certain super large keycap switch testers.

DSA inspired but clearly not curved at all to allow for printing flat upside down. It also doesn't have the bulgy square shape.

I find that the 1.3mm stem gap works best for me on my Bambu X1 for FDM but on resin prints 1.2 works a lot better as it flexes enough for a tight fit. For the protection of your switches I'd start with 1.3 and move to smaller sizes if it's too loose rather than go too tight and shave off a tiny bit of plastic from the switch stem.
