VERSION 2 now available : https://www.printables.com/fr/model/576763-fixing-lug-version-2
I did print it in PETG with a 0.4 nozzle, 0.3 mm layer and 100% infill.
But it is an easy print, you can change values to match your needs.
dimensions
- plate : 30 x 30 mm
- screw holes : 4 mm
- middle hook hole : 3 mm
- side hook holes : 4 mm
source files
For the sake of completeness, I did add the source files.
Python code generate SCAD files that you can then convert to STL.
You need MuSCAD (https://gitlab.com/guillp/muscad) to be able to run the Python code (pip install muscad).
EDIT 09/2023 : it broke !!! I am working on a version 2
My usage of those lugs is to maintain a spring which opens automatically the chicken coop door every morning.
It did work perfectly for several months, but the lugs did eventually broke under the repeated tension every night.

I guess the weakness is the layer orientation.
Version to will be tilted so that the layers will be perpendicular to the tension force direction.
