Binoculars eyepieces cover for Celestron 15x70, but also customizable

thingiverse

Replacement eyepiece covers for Celestron Skymaster 15x70 binoculars are available and can be easily adjusted to fit other models. In Openscad, the design allows for a snug fit on various binoculars. A small gap exists between the central connectors, but most 3D printers should be able to bridge this gap without issue. If bridging is not possible, low-infill support can be used instead. I personally find these replacement eyepiece covers to be more comfortable and secure than the original ones, which is why they have become my preferred choice.
