Watch opening tool 40mm

This opener should fit on all common 40mm watches with a threaded back plate. Some higher end watches need a specified torque value applied for closing, to be waterproof again afterwards. There fore this tool features a 3/8'' drive in the middle to fit your torque wrench.

Note: The notches have a 2mm size and fit verry tight. If you tend to over extrude, you might tune slightly towards underextrusion to make them fit better. 
For layers a 0.1 hight worked fine for me.

CHANGE LOG 23.07.2023:
Added a version with longer handle bars to give you more grip. The long handle version has the normal 2mm sized notches

CHANGE LOG 27.01.2023:
Added a version with “smaler” notches. Theyr size is reduced from 2mm to 1.75mm widht. Therefore they should fit much better even with slight over extrusion
