Eye cup adapter for mounting your Sionyx Aurora to helmets. Remove the basic eye piece came with your Aurora and put this to its place. I used Flexible Filament (%100 TPU) and it fits perfectly, you might also use a flex cuff to make it even more tighter. Flexible Filament is also resistent to BB impacts if you use it in airsoft. (I tested against 550 FPS with 0.20 BB, didnt cause a scratch)

I added both Left and Right eye versions. (Ofcourse designed with a reverse mounting of Aurora in mind. But you can also use the eye cup in normal mounting on picatinny rails)

These setting worked well for me with Flex: Temperature: 230 Platform: 65 Infill: 60 no raft / brim You might need some supports.
