Invisible Lightweight 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.

If you need a larger one, scale it a bit in y-axis. Check the preview to make sure it prints smoothly.

Notes:

I used Vase mode (spiralize outer contour in Cura). Line width 0.4mm or above. 0 bottom layer. Recommend to use a smooth PEI bed. A glass bed with bed temperature increased to 88 works too.

To print multiple at a time. Vase mode cannot be used. Recommend to print a single to ensure a good bed levelling and no "elephant foot" problem first. To ensure it prints smoothly:

• increase the extrusion width (0.52mm works with me) and look at the preview to make sure it only prints a single wall and no infill.
• set "Fill Gaps Between Walls" to Nowhere
• turn on "Filter Out Tiny Gaps"
• turn on preview of travel moves and ensure only single move to each model per layer
