I’ve designed a cable holder for the Zeiss Standard 20 microscope. It attaches to the back of the microscope and provides 35 mm of cable-wrapping depth. This helps keep things tidy, as the cable is otherwise typically wrapped around the entire microscope. The design allows for neat storage, keeping the cable nearly flush against the back when plugged in.

I recommend this version if you are the sole user of the microscope. If the microscope is used by students, I’d suggest using my other, more robust version instead.

Mounting instructions: To install the holder, you’ll need to remove the back panel of the microscope, which contains the electronics. Place the penal face down on a flat surface, with the inner side facing down. You will see that the transformer is secured with four screws. Remove these screws, align the cable holder over the existing screw holes, and reinsert the screws to fasten it in place.

You may optionally use screws that are 1 mm longer, but in most cases, the original screws will suffice.

PS the model is free to use but if you wone thank me I always in need of coffee
