Surgery Mask Support Frame

*** Edit: 20201027 ***
I have managed to print it on my glass bed which makes it much smoother when slipping in the folds of the mask. What I have done to make it stick to the bed are:

1. Increase the bed temperature to 88 degree C for PETG
2. Fine tune the Z-offsets with SET_GCODE_OFFSET command in Klipper

I have uploaded a v5 which is smoother. It can be printed in non-vase mode nicely. I have also uploaded an STL file with 10 frames printed together. This is what I used for mass production.

This mask support frame creates a space inside your mask to keep your mask away from your lips. You can talk and breath more comfortably with it. It also helps to tighten the left and right side of the mask to your face.

This tiny simplified one has a number of advantages over a full-size one.

• It is much lighter and you will forget it is there.
• It does not touch your face.
• It can be installed quickly and easily.
• It does not come off when you put on and off your mask (very important as it minimize the chance to directly or indirectly touch the inside of your mask).
• It is easy to print (pay attention to the printing note below).

This support frame only works with mask with folds that the sides. To install the frame, just insert one end to the one side of the middle fold and then the other. If you wear the mask correctly, the folds should hold the frame in place so that it won't drop when you put on and off your mask.

There are different size of surgery mask and this one is suitable for the largest one in hand. With a smaller mask, you can easily cut it with scissors. You may scale a bit in your slicer if a larger one is needed.
