DFRobot CM4 Routerboard Case

Files to build the case for the DFRobot Raspberry Pi Compute Module 4 IoT Router Carrier Board Mini (see: https://www.dfrobot.com/product-2242.html). I reviewed this routerboard in May 2021 (https://www.jeffgeerling.com/blog/2021/two-tiny-dual-gigabit-raspberry-pi-cm4-routers) and printed the case in white PLA for that video. It is a little difficult to snap-fit without a little extra sanding, but holds together okay. The cutout on the top is sized correctly for a specific model of CM4 heat sink.
