Duo-M by Duo Foundry

Duo Foundry is back with our 2nd project! Duo-M is a 75% spring mounted keyboard with a 3-layered case design, allowing for a distinct middle layer accent piece.
Through this IC, we hope to get your feedback on the colour preferences, design and an idea of the demand for this project. Kindly fill in the below form if you are interested! Many thanks in advance :)

Design
Similar to our first project (Duo-S), one of the main objectives was to try out a new mounting design. Spring mounts! (let me know if there was already another board with a spring mount)


To spruce up the looks and functionality of the board, we incorporated a scroll wheel. This can be programmed to adjust volume, screen brightness etc.

Also, we strived to achieve a distinct middle layer accent piece that could go all the way around the board and to give an illusion of a case within a case.

Alignment of the plate and PCB is in-built via the alignment rails on the middle case.

Colours
After considering the IC feedback, we have decided to provide for 6 distinct colours! You may mix and match the colours amongst the 5 keyboard components. This makes for a total of 720 possible permutations!
Colours: Black, Navy, Grey, Copper, Maroon, Silver
Keyboard Components: Top Case, Middle Case, Bottom Case, Scroll Wheel, Weight
