Set square

Here is a simple set square.
Dimensions: 35x60 mm.
After printing, slightly bevel the teeth of the frame to better fit in the vertical and bottom recesses.
I assembled the three parts with fast polyester resin (5 minutes) and they were aligned with the help of a metal square set.
I had to export the frame in OBJ format because the in STL didn't work. I dont' know why...
Designed with Rhinoceros.
