This is an interface for adding a USB hub with built-in SD and micro-SD card reader, and audio cable ports in two different sizes, to the right end of the keytar case. The part that holds the audio cables also covers where all the cables pass through the hole in the end of the case (where the cable for the original keytar originally came out). The 3 smaller holes that are already in the case are used for anchoring the hub to the case, and a couple more holes will need to be drilled in for the cable cover. The U piece is to help secure the regular audio cable in place, with a bit of glue after painting and install. There are a couple points where I'm not entirely happy with the fit, but it's close enough, and they are small enough issues that when I paint it might fill them in.

Materials and methods

I use an assortment of lengths of #6-32 stainless steel flat head machine screws, nuts, and washers for all the screws on the keytar. j5create USB C Hub adapter dongle: https://www.amazon.com/gp/product/B07DX7MWZ6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Audio splitter: https://www.amazon.com/gp/product/B07431YDWM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 Audio cable extension: https://www.amazon.com/gp/product/B01K3WYLUO/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Audio cable adapter to 1/4 inch cable: https://www.amazon.com/gp/product/B07QLGYW3H/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 USB-C to USB-C adapter: https://www.amazon.com/gp/product/B071WW2K47/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Any USB-A to USB-C cable (for data from the pi) Any USB-A to micro USB cable cable (for power) The USB-C to USB-C is to connect to a USB-A to USB-C cable coming out of the raspberry pi (I needed the USB-C to fit through some of holes in parts I had already designed). I recommend disabling the power wire in that cable to prevent power backfeeding into the pi, as you should connect the hub to a power source to prevent power load on the pi.
