The file 'Homemade Nikon TC-3E ED 3x Bino Holders 3D Printer Model' is (stl) file type, size is 3.2MB.
Convert two Nikon TC-3E ED 3x teleconverters into binoculars. Wide true field of view 3x low power binos. I used PET-G 150 stereolith.
Since these do not have focusers you will need reading glasses (not long distance glasses) to focus if you require reading glasses.
Caution, some people's IPD (pupil distance may be small and require filing away inner contact point of teleconverter outer ring (not the stereolith part) to reduce this distance.
