I created this parametric OpenSCAD drilling template to help me mount an inset door into a cabinet using some Blum inset hinges. Adjust the “inset” variable in the OpenSCAD code to suite the thickness of your door. I've provided STL and 3MF files for two common door sizes: 18mm and 22mm. I learnt how to mount these hinges having watched Peter Millard's excellent tutorial - see below.
The author marked this model as their own original creation.
