Casio AE-1500WH 18mm to 22mm Band Adapter

First, just a disclaimer that I have no idea how durable this will be or if you'll lose/damage your watch using it (plus it depends what you print it out of). I did have one of the secondary spring bars pop out once, but I have no idea if that's just because I can't do detailed enough printing at 0.4mm

Anyways, my goal was to make the walls thin enough so the adapter can rotate a bit too (didn't want any sort of lever action) which probably compromises strength a bit. Would've rather bought a metal adapter if I had any luck finding one that did 18 to 22, but I guess upside of this is it's as wide as the watch case. I should also mention you do need additional 22mm spring bars for this design.

I printed this with an Ender 3 Pro at 0.16mm layer size with a 0.4mm nozzle with maxed out walls. Found it very annoying how finnicky prints at this small of a size are with my printer, so I basically played around with numbers. Whether I get the actual dimensions from the STL is very questionable...

Also added an additional version with quite a bit less clearance between the watch case and adapter. Still is able to rotate though. This is the one I'm probably going to use.
