COVID-19 masks headbands - setting/testing
Prusa Research developped a mask to fight COVID-19; that can be printed on our 3D printers.
There are initiatives in different countries to participate in a mass production, and enterprises put their printers at disposal.
J O I N ! ! !
Based on the original Prusa files, I developed a tool to check the settings of a 3D printer for production of the Covid-19 masks headbands, without loosing time and materials.
PETG seems to be the best material.

Notes:
I used the original file fromm Prusa dated March 25, 2020.
You can print a partial headband, limited in horizontal and vertical sizes.
The ready STL files are shown on the pictures.
If needed , you can do your own cuts with the OpenScad customizer, change file name, a.s.o.
The scad file is named RC2-part.scad.
I included the STL file that I used as rc-orig.stl
Be aware, the SL is vertically centered, so start with TH=-30, TK=60 to have a full view.
You can re-center the original file. I had to move 840mm withthe file I used.
At start, use the "View all" button of OpenScad
The base settings show a bit more than the 'CUT1' example.
If you do not see anything, try to set "Partial rendering" to "no" ! The cut part could be empty.
Technical remark: the stl file used allows the rendering after import and manipulation. Not the case with all stl files!
