I finally finished the case!! After I trimmed the sides of the case to fit the Seeed XIAO RP2040, I also made the holes for the screws larger to fit the head inserts. I also made some corners around the sub c socket so that it would not wiggle around when I plug it in. I made the around the usb c socket larger to have enough space to fit the head of the cable around the usb c since the socket does not hang at the edge of the case. I also cut out the holes for the switches using the plate model and cut out the oled display space as well as some extra space underneath it to fit the other parts around the oled that are going to be inside the case. In the end I also curved the edges of the case and socket. I had some trouble figuring out how to use fusion but I’m slowly getting the hang of it. Over all I’m pretty pleased with how the case looks!! I also made sure that the 5mm heat inserts would fit and have some extra space left.
