This is a helmet in roman style for the popular dummy 13 model. It fits the standard head, and is an over head armor (much like a real one). This is the rounded version.
Edit: Chamfered/classic look can be snagged here if you prefer a more blocky/boxy style: https://makerworld.com/en/models/444376
This is my first model made since i got the A1 mini printer, so do let me know if something is off. The file should work for ASM, but I do not have the system, so feel free to try it and let me know! If you have no ASM, just remove the filament colors and pick just 1, it should print like I have in the pictures. (I only have silver pla at the moment, hence the very monotone look.)
