Some of our developer kits shipped with a little 3D printed enclosure to keep your USB programmer a little more safe in places with spilled water and the like, but we stopped producing them when we took our office remote due to COVID-19.
The Dev Kits we ship are just as functional without these cases but if you are interested in printing your own or having a friend print one for you, the files can be found on Thingiverse here:
Feel free to download it, print it, remix it. There are a bunch of other tools and jigs we have used in the office for various applications so we can share more of those and I would love to see some community designed tools, maybe even one that can make programming Blinks a hands-free operation?!?
