Love that certain Casio mod that has it encased in resin but hate the lack of functionality / environmental impact / short sightedness of it?

Here's the solution! It's a STEP file, so you can choose to print this in clear resin such as UTR8100 through PCBway or you can choose to have it machined in Acrylic!

It works with original backs but uses M2 screws so that you have the option of polycarbonate (https://www.accu.co.uk/phillips-countersunk-screws/655280-SIK-M2-4-PC) to keep it looking clear.

There are also 2 versions one with buttons on the side, that reuses the ones from your original F-91w and one that doesn't have buttons for those wanting the most minimal option.

I'm in no way affiliated with SolidState, this project uses the design principals but an entirely different method of manufacturing. The case was modelled based on my own work with the F-91w reproduction casings I have been working with with the addition of a domed top - this is a work of homage / parody to that design.
