These optically perfect sheets are actually upcycled X-ray film. We were lucky enough to get our hands on one last set... the exact same ones we donated back in March and April. These PET sheets are pre-cut with rounded corners to 9.5" x 11" (perfect for the American Prusa or the 3D Verkstan headgear). They are packaged in bundles of 50. To punch a hole, simply use a standard, household hole puncher, which will cut right thru. Then attach to your 3D printed head gear.
Minimum order is 2 bundles: 100 sheets. So, $55 gets you 100, which includes delivery to your home, makerspace, or place of business.
Here until sold out.
