UPDATE: I pulled this for a while, until I could build in some protection for the antenna. During my first flight test with this case, the antenna got hit and bent the SMA connector up a bit. The tracker was not significantly damaged; we walked right to the rocket; but there's no sense beating up the electronics by exposing the antenna without support.
I've now included what I'd call a "jam ring" (kinda like a jam nut" which you tighten between the case and the antenna. Since everyone's antenna is different, you might have to experiment with the design to get it just right. Maybe change the height of the ring at slicing time 'til it's just so.
Another issue: I realized on first flight that the attachment loop is printed so failure could occur if layers pull apart. I reprinted the cap on its side, so that the loop wouldn't be weakened by layers, but now it looks like the is held together by a tiny piece of extruded plastic. 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 necessarily different) is in order to determine what's worth using, and how much pull it can take.
This is a side-by-side case for the Eggfinder Mini GPS tracker, commonly used in model rocketry.
This case is an attempt at reaching the most compact volume for the mini in a short length. I'll sometime try a longer, narrower arrangement, and I already have a lay-flat arrangement for payload bays in 4-inch rockets (will post the latter sometime soon).
The hole in the side of the case is so you can see if there's a battery in place.
I used a SMA mount for the antenna. You may have 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.
Materials and methods
I printed with 90% infill, the only support was on the case plug, which was printed upright.
I think I found the attaching screws at the local Home Depot (if non-US, Home Depot is a US big-box DIY home repair and maintenance supply store). The smallest ones they had.
