Safer opener for Casio WQV battery compartments

Problem

The WQV-1, WQV-2, WQV-3, and WQV-10 watches have an "easy access" panel to replace the CR2032 watch battery, as these camera watches are power hungry. The panel seems meant to be opened with the edge of a CR2032 battery itself. But the panel is made of super soft plastic! It's extremely easy to put a nick in it when using any kind of tool.

Solution

Print this instead! It

1. Gives you better leverage and an easy grip
2. Is a nice tight fit with the slot
3. Plastic-on-plastic won't damage the panel!

About

This is part of my QV1ckenIR project, a modern, USB, easy to use self-contained sync dongle for WQV camera watches. If you buy one from the store, this opener comes included free as a little bonus!
