Komobi proximity keyring replace

I just broke the little plastic placement of the keyring on my komobi proximity keyring and had to wear it on my pockets.
Komobi sent me a new one, but I decided to try to creat some sort of enclosure that could be more sturdy.

Obviusly the device slides in, as it is a snug fix on my printer (has some 0,2 - 0.4 tolerance issue) I recomend a little drop of glue/hotglue so you can remove it at will if needed.

Hope it helps someone
