These reversible hinges work great for all sorts of projects.
The model is a quick print-in-place and needs no supports.

Printing Recommendations: 
0.2 mm layer hight, please turn off supports, 15-40 % infill, 3 perimeters. 
PLA will work fine, as usual for a more temperature resistand result use PETG/ABS.

Tipp: The model also functions as a printer test, espcially for tolerances.

The holes on the hinge have a diameter of 4.2mm and a 7.2mm countersunk head.

Hope you enjoy using this model as much as I do.

Happy printing!
