Using jblake's dimensions of his reinforced opener, I redrew it in Fusion 360 so I more quickly scale to different sizes while keeping the thickness at 14mm and the “catch tabs” at 2mm.
This is the 73 mm model in the collection.
Printing notes:
PETG
0.2mm layer
20%, rectilinear infill
3 perimeter layers
No supports or brim
If you have any needed size in the final collection, let me know and I can create it if you like. Just send a message in Printables.
The author remixed this model.
Redraw to Fusion 360 from the STL file. I needed to be able to scale to different sizes then cut or extrude so each new size had the same, 14mm, thickness
