NP-25 Calculator 3d case and keys design
I've posted the .stl files and assembly instructions for the NP-25 calculator case and keys on Thingiverse.

Oh, thank you for the explanation, the symbol choice is a combination of the readily available font and limited time to find a work around. The proper division symbol did not print clearly with the equipment I am using. All of the key legends could be made clearer by printing on a resin printer or using a smaller nozzle diameter on an fdm printer. Try CC41! |

It's strange that "\" prints out better than "/" while I understand that "÷" can be problematic if resolution is coarser. Greetings, Massimo -+×÷ ↔ left is right and right is wrong |

RE: NP-25 Calculator 3d case and keys design
Here is what the keys look like with an obelus symbol. The 'dots' above and below the horizontal bar did not print well on my 3D printer so it more resembled the minus symbol. I've sent this to a friend who has a resin printer to see how well it prints.
