Hello everyone, I've spent the last couple of months working on a Runcam 2 4K shroud for my universities SAC 2 stage project; we put one camera on each stage with the booster stage facing upwards. The shroud is 3D printed in a couple of parts that bolt together using 2 M4x18 bolts. There are two versions of the shroud, I call them "Down Mount" and "Up Mount". The "Down Mount" is the more standard variant, the camera slides in and out from the opening in the front and clicks into place using the sled that came with it. The "Up Mount" is a bit more special; the central portion that the camera slides into is shorter and there is a shroud that bolts in front of the camera using 2 M2x12 bolts, this allows the shroud to be mounted facing upward in flight. Both have a 5 degree upward tilt that allows the video to not be 1/3 body tube.
Runcam includes an orange sled that I designed around. I figured Runcam knows their camera dimensions and retention better than I ever will. Using the included sled allows the runcam to be easily removed by pushing on the back of it with a small tool (I use the back of tweezers, but a flathead could also do it). With the "Down Mount" no unbolting is required to get the camera out. You can see the little slot for that in the image below, there are also cut outs that line up with the power/wifi buttons; all operations are possible without removing the camera. Theres also a little space in the back that may allow you to hook a usb cable into the camera while its attached although I haven't tested that.
I intend to release all STLs for this project here and possibly on thingiverse. Right now its designed to fit on the outside of a 5.5" blue tube, I'd like to make versions for as many body tube diameters as possible. I'll get some posted with diameters I think are most common, however if there is a specific diameter you want please let me know and I'll post that as well. The following post in this thread will contain a table with all of the files needed, as well as an assembly guide (once I make it).
For now, here's footage of our 2 stage launch last saturday using these shrouds. Unfortunately the sustainer didn't light, so its more of a complicated single stage.
