This design is made with 3d printing in mind. It uses no supports and can be printed very easily although I brim for all the parts to prevent warping and in the case of the knobs, popping off while printing. I used a usb-c Arduino pro micro board that is taped to the raised section of the base. I found doing it this way allowed for space around the wires that i soldiered on while being firmly kept in place. The top plate is just held in by 4 M3x10 screws and has access holes in the bottom panel to screw into the top as hidden screws (I strongly recommend getting the screws partially in just so a slight lip is outside the bottom plate and then putting on the top plate as it allows for easily alignment with the holes fitting in place and makes it easy to attach the top panel. I used standard Dupont wires for attaching the sliders with the exception of the last slider on the right due to limited space I just soldered the wires to the leads. The sliders are screwed in with M3X6 screws. Lastly, rubber feet are a great addition to this if you are willing to get some for it as it makes it not slide at all giving it a more premium feel and making it a better user experience.
