Unleash the power of classic comic book villains with this Old-School Sentinel Helmet, inspired by the legendary Sentinels! Designed for 3D printing, this helmet captures the bold, mechanical look of these iconic mutant-hunting machines.

This set includes all necessary STL files and my custom 3MF file for Bambu Slicer, optimized for the Bambu Lab A1, P1S and X1. The model is designed for easy assembly, featuring a press-fit or glue-in system for 6x2mm round magnets.

For best results, print all parts in purple PLA and the faceplate in light rosé PLA. The dome remains uncut for a seamless, clean look—meaning the backplate installation can be tricky. It’s easier with a second person helping. Also, due to the helmet’s high profile, padding is highly recommended to align the eye holes correctly.

⚠️ Fit Warning: If you have a large head, you’ll need a 300mm print bed, as the helmet is a tight fit on the forehead.
