Making Face Shield using 3D Printer (COVID-19)

Making Face Shield using 3D Printer (COVID-19)

The 3D-Printing Community has been making some items to help with the needed shortages caused by China's COVID-19 attack.
Find some info here: https://www.youmagine.com/designs/prote ... 3dverkstan
There are several Face Shield Frame designs and I have made some of the North America 6 Hole and North America 3 Hole versions.
The 6 hole frame works a little better because it holds the shield firmly in place
and with the 3 hole version, the shield can shift diagonally back and forth.

The 6 hole Shields are more difficult to make the holes to be spaced correctly
and with the 3 holes Shields there is no difficulty getting the holes spaced properly.

3D Printing Frames for face shields
1) Download the zip Face Shield file and unzip it.

2) Open the STL frame file to your Slicer program and make your setting.
Some suggestions for the Slicer settings:

3) Send your G-code to Printer and 3D Print the Frame.
Note: I was able to easily fit two frames on my 310mm x 310mm print-bed.
I decided to make the North America 6 Hole Face Shield versions.

Making the 6 hole Face Shields
What can be used for the clear shield ?
I have a few sheets of .007" thick by 29" by 40" clear plastic sheets
and I cut them up into 11" by 8 1/2" sheets.
Note: When making the 6 hole clear Shields it is very important to hold the 11" length,
as when this is longer or shorter will cause the location the hole to be off a lot.
The best sheets may be A4 Sheet of Transparent Plastic (overhead-projector) like:
https://www.amazon.com/OHP-Film-Overhea ... B078QYKNKG

1) Using a 3 hole paper punch, slide the 11 inch by 8 1/2 inch clear shield
back from the Punch-Stop, about .531" (17/32") so that the center of the first hole
is .750" (3/4") from the edge of the clear shield.

2) Punch the first set of 3 holes.

3) Next, flip the clear shield end for end by the 11 inch length
and repeat setting this other clear shield edge .531" from the Punch-Stop.

4) Punch the second set of 3 holes.

5) Hopefully this method will achieve placing the 6 holes to there proper places.
This method did not always work correctly for me as some holes were to far off.

6) The fix that I used, was to use a hand Single-Hole-Punch and by eye
re-punch to incorrect the hole so to be larger.

Update Note about punching holes, see here: https://openrcforums.com/forum/viewtopi ... 54#p149454

Note: Some people are 3D Printing a special spacer that will make the first hole center
to be at .750" (3/4").

This youtube video may offer some helpfully info with making the face Shields:

Update Note: I found that when punching the 6 holes using the 3-Hole-Paper-Punch,
1) I position the Clear-Shield for the first set of 3 holes a little more forward and punch holes,
then slide backward a little more and punch holes again.

2) Next I flip the 11 inch long Clear-Shield end for end and repeat the same process for the second set of 3 holes.

This make all the holes oval shaped, which helps a lot with the holes that are not being punched in there proper places.
Oval shaped holes fit better.
Oval shaped holes fit better.
Also with hand scissors, I trimmed the 4 edges of the Clear-Shield sheets.
