Tools(s) to open radiosondes. Mechanical tools.
Locally, folks have been recovering NWS radiosondes. Specifically, Vaisala RS41-SGP sondes. (And reprogramming for a nearby amateur radio band and re-flying them.)
These are held together with a couple of plastic clips. Sure, these can be pried open, but it seemed like an interesting design problem to come up with a clip release tool.
The lower clip was easy, and works great as a 3D printed tool. The clip releases with a satisfying click. Design can be found HERE.
The upper clip is more stout. A two stage procedure seems to work well with 3D printed tools. No satisfying click unfortunately. Design can be found HERE.
