This is a brain hat originally from Thingiverse by romroig (thing:1811251). All credit goes to him.

I prepared then painted the model in Bambu Studio and tested the print. It is designed for an AMS and uses 3 colors.

The very top of the underside will have a small amount of stringing as it bridges that area. No support is needed as you do not see the underside when it is on your head. You could add a support there if you wish but that will cost extra time when printing.

If you are not happy with the fit just scale it to suit (not everyone has the same head size).

Filaments used in the photos:

• Bambu Lab PLA Basic Silver (head band).
• Bambu Lab PLA Basic Dark Gray (screws).
• ELEGOO PLA+ Pink (the brain).
