It's basically the watch stand by Chuck Bryant with a solid 1mm layer on the bottom to place the chain of my watch so I can lift it and move it without it falling through the hole.

Print with the back on the build plate with the hook pointing up.

I printed it with 0.2mm layer height BUT adaptive layers on so not really 0.2, I used supports but the original maker says it doesn't needs them, 15% infill.
