Plastic Buckle (Designed for 3d printing with zero supports)

Outside dimensions of the model:

The holes are 6mm x 11mm 

This is version 5 of a plastic replacement buckle that I designed with the FDM 3d printing process in mind:

1. No support is needed 
2. Prints in only 30 minutes 
3. Optimized print orientation for strength
4. Designed to counter possible elephants's foot
