The Predator Inspired Movable Mask
3D model description
This is my first mechanized mask (version 2.6).
The mechanism doesn’t contain electronic components.
A human jaw sets the mask lower jaw in motion then the movement distributes further to drive the other elements. Watch the video tutorial to see how it works: https://youtu.be/1uUUhSKz1iU

3D printing settings
All the parts are ready to print, split and placed on a bed the most optimal way.
It’s intended to be printed out of PETG (otherwise the mechanism might not work because of different mechanical properties of other materials).
Recommended printing settings:
Layer height: 0.2mm
Line width: 0.4mm
Wall line count: 3
Z seam position: at the top right corner
Top layers: 3
Bottom layers: 2
Infill density: 20-35%
Support generation: off
You need at least 170x145x115mm build volume to print the model.
To assemble the mask you’ll also need:
M4 screws with countersunk head, 16 mm in length, 4 pieces;
M4 nuts with nylon ring, 4 pieces;
neodymium magnets, 10x1.5mm, 26 pieces (or 10 pcs of 10x3mm and 2 pcs of 10x5mm, in this case use files from “For_3&5mm_magnets” folder)
nylon cord, 0.5-0.8mm in diameter, 3 meters;
nylon strap 2cm in width, 1m;
self-adhesive EVA foam, 4mm thick, at least 2x10cm piece (such foam is used for handmade cards, shapes and letters, if you can’t get 4 mm thick sheet try to find 2 mm thick foam and use 2 layers of it bonded by hot glue);
fishing line 0,3-0,4mm in diameter, 0.5m (UPD: now you can use a 3D printed line, the file is in the pack, just straighten it after printing, fold in half and use the same way as fishing line loop);
Velcro strip, 2cm wide, 0.2m;
black elastic fabric (the most simple solution is a couple of socks), 8x6cm piece.
Watch my video tutorial to assemble and tune the mask step by step.
To be sure the mask will fit your head, first measure your head width (above ears), then in accordance with this value use following scale percent for 3D printing (choose the nearest bigger value):
13.5cm - 90%
14cm - 93.34%
14.5cm - 96.67%
15cm - 100%
15.5cm - 103.34%
16cm - 106.67%
Contact me if you don’t know how to make this measurement or your value is out of the range.
File formats: OBJ, STL
The mesh was checked for errors.
UPD 31 Oct 2022: If your Cura slicer ignoges tiny spiral springs find a checkbox named "print thin walls" in Cura settings, chapter "Walls". First make it visible in the panel and then turn it on. If you use another slicer or this method didn't work for some reason please contact me.
