Update 3rd of December 2024:
Added a new generator for double supported wall hooks and a profile for a 40 mm door. 

Click Customize and select “Double Supported Door Hook Generator”.

Update 1st of December 2024:

Added optional support for the hook. It adds a bit of length.

Simple door hook generator based on OpenSCAD.

I've also included a print profile for the default door hook with 40 mm door thickness. It is suitable for 39 mm doors as well. Might be a bit wobly for 38 mm doors.

Depending on your door clearance, you can specify the top_thickness separately from the rest of the hook thickness.

I am open to any improvement suggestions.
