Customizable watch opener

2025/03/03 update:

Added Version 2 with these improvements:

• You can now set a customizable label for Watch name or size.
• Chamfer handle edges so it's less sharp and won't hurt when you use it.

==========================

I need to change the battery in my CASIO MDV-106 diver watch, but I doesn't have an opener on hand.
3D print to the rescue! I downloaded Chuckdotdot's OpenScad file, modify it to fit my watch, get it printed and I my watch is opened 40 minutes later.

Since I had some time, I optimized his SCAD script to support customizer, simplify it and add ability to change number of pins. Now you can easily customize it to fit your own watch!
