You will need screws M4x12 6pcs, M4x16 2pcs and 8 nuts for them. To make holes I used drill for wood 4mm in diameter and electric srewdriver. After you drill holes, print models and assemble all with your glasses you probably will need adjust part of the model and print again, because your face and glasses will differ from my. Update: I've added one more version (V2) that keep glasses 5mm far from eyes than previous version (on photo previous version). This version more comfortable for me, but for some people prevous version may be more suitable.For this version recommended to use supports. I've printed without supports and they are fully functional, but with them parts would be more accurate.
