Caveiras "Ceifador" Skull mask

Printing the mask Scaling is approximately correct for a 57cm head circumference Print both parts with teeth facing up 4 cuts of 1.75 mm filament approx. 2 cm long are needed to connect both parts. The pieces within the teeth should be glued in as dowels, the ones at the jaw hinge should be hot riveted Supporting pieces You can use the head strap from a 3M or similar respirator to wear the mask. I do not recommend medical mask straps The chin bumper is needed to stop the mask from sagging and to increase comfort Print from a soft TPU with zero top and bottom layers and one wall. Experiment with infill density to get the right comfort Chin bumper V2 might not work with zero top layers
