Hi yall, it’s been a while. I made a shell design for the card from the official 3D printable expansion card shell CAD, and test drived it for some months (on a non-framework laptop, since framework does not sell to my region). Happy to report that the electronics is reliable enough for my use. On average I get ~20 Mbps down and ~7 up on 2 wimpy FPC antenna, which is still good enough for remote desktop access and youtube playback. ![image](https://us1.discourse-cdn.com/flex001/uploads/framework3/original/3X/3/e/3e3930ae63a37f4eefea6b39ae888db2410a7e4a.jpeg) ![assembly-angled](https://us1.discourse-cdn.com/flex001/uploads/framework3/original/3X/3/0/30841696ce0ad6daf7333f9b019464ab68f9e107.jpeg) This was printed with JLC3DP’s 3201 PA-F nylon SLS. I’m not a mechanical engineer though, and the shell must have a lot of things that should have been designed better. As I don’t have a framework laptop, I also could not test fit it in an expansion slot. Anyway, I have published the 3D shell design in the [git repo](https://github.com/Zokhoi/framework-cellular-card), feel free to do whatever. --- _[View the full topic](https://community.frame.work/t/lte-cat-4-cell-modem-card/9454)._
