Watch Press & Crystal Remover/Replacer (Updated)

You use this to remove and replace the watch crystal (also known as the watch glass). Here's a video on how to do that. Make sure to go really slowly when twisting the screw to make sure you don't crack the glass. I basically just copied tools like this that you can find on amazon/alix. Can also use it to shut press-on case backs.

Make sure to print it on its side so the force doesn't pull on the layer lines. Same thing for the screw piece, cut it in half along its long side and print it that way. I recommend using some sort of strong filament, like petg or asa.
