Version 2 (suggestion by Andreas Kopp and coded by Mang)

4 pins to punch with a 4 hole punch. Holes from top are 1.2 mm.

Here a bit about Punching Holes: https://de.wikipedia.org/wiki/Locher#%E2%80%9E888%E2%80%9C,_4-Loch-Erweiterung_von_ISO_838

The two middle holes are set with ISO 838 like if you fold a pice of paper in then middle and the two outer holes are set with 80 mm spacing. So all holes are 80 mm apart.

Version 1 can be stacked to fit more pieces on a single print plate at the same time. 2 pieces next to each other.

Update: threre is now a version that does not need support and has no holes for easier printing

Update 30/03/2020: There is now a fusio file as well

Visor:

We use A4 Binder Covers at least 0.18 mm better 0.2 or 0.25 mm instead of 0.5 PET or PETG as its easier to source and cheaper. Drawings are uploaded to the file section.

Our aim is to provide this shield to as many people as possibile that do not need the deluxe Prusa Version and prefer a lighter version. This shield can be crowdproduced.

4 Hole puncher: Set to 888 and punch 1x

2 Hole puncher: Set to 888 punch turn around punch again

Other Mateials: 2 x 2mm 50mm Rubberbands

It works with PETG or PLA.
