We used to print PRUSA shields in Germany, but due to a large amount of complaints and problems we revised the design and made a multitude of changes. These include:
Reduced Weight / Better Weight Distribution
Increased Flexibility / Less Brittle Build
Rounded Edges / Larger Contact Face
Easier To Sterilize
A6 Punch Compability
All these changes have been included over the last two weeks and ended up in this design, which is currently used in German Red Cross and St. John Ambulance.
This is free to use, free to remix, free to everything! No Remix! The entire file has been created by us!
If you print this: Print in PET/G!!! PLA cannot be sterilized in any way. PET/G on the other hand is certified for over half of the common mehtods!
The last two pictures are old Renderings (the holes have been closed a few versions back!)
