Eggfinder Mini GPS Tracker side-by-side enclosure

UPDATE: I put this project on hold for a while, waiting until I could add protection for the antenna. During my first test flight with this case, the antenna got damaged when it was hit and bent the SMA connector. Fortunately, the tracker wasn't significantly harmed; we walked right to the rocket but there's no point in beating up electronics by exposing the antenna without support. I've now added what I'd call a "jam ring" (kind of like a jam nut) which you tighten between the case and the antenna. Since every antenna is different, you may need to experiment with the design to get it just right. Maybe adjust the height at printing time until it's perfect. Another issue: I realized on first test flight that the attachment loop is printed so failure could occur if layers come apart. I reprinted the cap on its side, so that the loop wouldn't be weakened by layers, but now it looks like a tiny piece of extruded plastic holds everything together. It's hard to know what's right in this case. I think some destructive testing of the part, by me, and by you (since your printer and materials are different) is needed to determine what works and how much force it can handle. This case is designed for the Eggfinder Mini GPS tracker, commonly used in model rocketry. It's an attempt at reaching the most compact volume for the mini in a short length. I'll try a longer, narrower arrangement sometime soon and already have a lay-flat design for payload bays in 4-inch rockets (will post that later). The hole on the side of the case allows you to see if there's a battery in place. I used an SMA mount for the antenna. You may need to adjust the position of the antenna mount on the board (or edit the STL) to make the rectangular cutout match up. You can probably just feed the wire stick antenna through the hole and not worry about it.
