Visor Style (same base unit with 2 links in the back)
Type A: Simple groove (best for rubber bands or other wrap around elastics)
Type B: Weave (best for using your stock IV tourniquet or other fabric; just snap out the bits you don't need for spacing)
- Minimal build time
- Single part + Mylar sheet
- Use your own band (IV tourniquet or elastic band)
- Requires measured 1/4" hole punching on the 12x12 mylar sheet
- luckily most hole punches are 1/4"!
- Reducing build time in the frame means the top is less protective; but then again; the bottom is wide open; so in theory this doesn't mean much. Adding material back into the space adds about 20m of build time.
Visor Type A STL v3.24.20
Visor Type B STL v3.24.20
12x12 mylar sheet; get 6mil if you can; 4mil is a little thin (albeit light)
I trimmed one end down so its 12x8" seems to hit my chest less often on movement; else just shift the plate upwards when you cut holes
Easiest way to space the holes is to put the device flat on the paper; and punch two holes so the front 2 fittings are snug. Then roll one way and then the other until the sheet touches the prong and mark it with a marker.
I used 2 elastic cloth bands; you can buy 16 yard rolls online or at a craft store; and use fittings (i'll make a file for you to print); for now I'm using a fitting I pulled from another type of mask).
VERSION 2: To be posted tomorrow
This version will use a slide in function for the mylar; so you do not need to punch any holes; just slide it in and it will "pinch" along the sides. I got the idea from Tarek's design.
I have also widened the grooves for the back end to fit a tourniquet; and will add fittings you can attach to the other side of the tourniquet and make a hook (so you can clasp the back together.
