Created a gun stand designed for a shelf.
2 versions available: split and solid. Solid version is meant to be printed standing, while the split one is for horizontal printing.
Split will have better details and print time but worse base finish and requires 2 M3×18 – M3×25 (DIN 965 / ISO 7046) per stand. Can also be printed without the second part.
Solid will have nicer base but will print slower and have worse overall details.
I'm not sure if it will work for real guns as I don't have access to any.
