Summary

*UPDATED TO VERSION 2.2 on 30th May 2020
Modifications from V1:
-Enhanced grip of acetate
-Higher nose bridge
-Slightly longer temples
-3 part version clips together without need for glue.
-Added Size L temples to split version.

Simple protection visor created with a 3D Printed frame and a clear acetate sheet.

You can print the frame as a single piece with the VisorV2.STL file, if the printer allows for a volume of 151mm x 160mm x 35mm

There is also a version with longer temples for larger heads: VisorV2-SizeL.STL
Printing volume: 151mm x 181mm x 35mm

If you have a printer with a smaller printing volume, I have split the visor in 3parts too.
In this case use the VisorV2-Split-center.STL, VisorV2-Split-left.STL, VisorV2-Split-right.STL files. For the Size L version with longer temples, use the VisorV2-Split-center.STL, VisorV2-Split-left-SizeL.STL, VisorV2-Split-right-SizeL.STL files.
In order to assemble parts, insert the left and right temples from below on the central part. Push them firmly to lock. If needed, use a hammer (check images for reference)

After printing the visor frame, just add a clear acetate/plastic sheet to cover the face.

DISCLAIMER:
This is a very simple frame and the only protection it provides is the fact that it keeps a transparent plastic sheet in front of your face. It can't compare with any certified health product. It is just a means of providing protection when you don't have access to certified material.
