33mm watch back case opener tool

3D printed watch back case opener tool, specifically designed to fit Casio watches (casio 240 DW-5200). The tool has an outer diameter of 39 mm, with 33.3 mm between the notches.

For best results, it is recommended to print in a strong material like ABS. Increase infill to 75% and use multiple walls to improve durability. Note: the notches are thin to fit the watch case and may break if handled roughly.
