- Easy to print and customize to fit your setup.
🛠 Printing Specs:

- 0.2 mm layer height
- 0.4mm nozzle

🎨 Personalize It Your Way:
With the included Fusion360 source file, you can tweak the design to match your gate handles perfectly.
EDIT 16.09.2025:
Fusion360 is dropping support for windows 10 and I do not want to update my PC just for that.
I will stop any further modeling in Fusion360.
I remodeled this completely in Freecad and uploaded the source file as well. Enjoy !
