This is a holster for my secondary Ford keyfob with a clip so I can store it somewhere as a backup. It's sized to snugly fit the 5 button smart key for my mid 2010's car, other similar models should work.

I printed this in PETG. You should print it on its side such that you can view the profile of the clip from above… i.e. so that the clip is stronger and layer separation won't snap it off.

Take note that the fit is very snug, you'll want to be sure no button is being held down when in use. I use this to hold a fob with no batteries, so this is not a concern.
