Acura TL Keys Case

I've got a 2008 Acura TL and the key's spring started fading on me which was annoying, so I designed a case for the key and a case for the fob. The key case has too parts which are superglued together for a permanent fit. The fob snap fits tightly into the case but it can be superglued in as well for extra security. I printed these out of high infill PLA on a Printrbot Simple Metal and have been using the PLA parts for about a year now without any sign of damage or any instance of breaking.
