Shell for making 2x54 binoculars from two Nikon TC-E2 teleconverters.
Use M5 socket cap screw with flat nut for the axis.
I'm printing the eyecup with soft gum filament and 1% infill with 2 perimeters so it stays soft.
Update: added gopro adapter. Remember to use longer screw to mount it.
Update: added tripod adapter. Print to copies, insert M5 and 1/4" nuts then glue parts together. You will need 25mm long M5 screw too.
Update: added non-winged version of the eyecup
Update: new thicker version of the eyecup.
Update: New version with bigger space for nose. Strap mounts are now better positioned and stronger.
Update: I've added stl file for eyecup to print with elastic filament (gum, tpu)
Update: I've added another version with strap mounts.
