B2-EMO V2 Eye Buck for Vacuforming

Eye Buck for Vacuum forming his main Eye. NOTE: This model is for his eye lens.  It is NOT the eye (shown in green in the photo.). I used .5mm clear PETG in a two stage vacuum-former at 150degrees C.

I used a good pair of scissors to cut out the part.  Remove the part by cutting the "flat part of the plastic then carefully make a few thin circumference cuts.  The Final Cut should be at the bottom of the small dots.  I did two of the eyes at the same time and put a small item on the bed to prevent wrinkles.  Plus, you will have a spare eye.

Spend plenty of time sanding it “glass” smooth.  excessive layer lines will be reproduced in the eye if they are present..  Also, print in a low layer height.  I used .1mm.  I used 4 perimeters and 9 top layers with a 25% gyroid infill.  I printed the bucks in PETG.  I got dimpling on my PLA+ test piece because vacuum sucked so hard and the PLA got just malleable enough it actually created dimples where the infill had gaps underneath.
