Invisibility Lens

This model uses a lenticular lensing effect, which can create a powerful optical illusion, if executed correctly. The circular design I created can make it even more convincing, as well as having a nice look to it. Transparent filament is a must, either PLA or PETG should work fine. The 0.2mm layer height is important for the best effect. I highly recommend printing at 20mm/s for quality. Taking extra steps to dry filament can help a lot too.There are two supports that print around the side which came off pretty easily for me, but you want to be careful as the lens is very thin. They enable the ring to print nicely all the way around the top
