About This File
No supports required except for the back of the eye, remove supports on this part and insert the ring which is for aligning the front and the back of the eye.
You may need to reduce the size of the joiner to 99% to help it fit into the recesses, do this in your slicer and scaling.
I recommend 20% infill and 3 perimeters. Send me a PM if you need assistance!
11MM diameter hole is for the eye stalk/pivot files which I'll upload soon, the finished prints are kept together with an M10 threaded bar and nuts.
