Ford Key Fob Clamshell Cover (Updated)

Updated August 1, 2026: After some feedback, I made a couple of small changes to the design-

1. Tweaked the geometry to make the cover much easier to disassemble.  It can now be assembled and disassembled many times without damage or wearing out the snap-together geometry.  Note that you must have good layer bonding and use a filament that isn't brittle.

2. There is now a "window" version of the logo-side cover that will better display the logo on Bronco or Mustang fobs.

I got tired of accidentally setting off my Maverick's panic alarm when my key fob in my pocket pressed against something, so I set out to design a cover that would partially cover the panic button.  This is what I came up with.  The cover is printed in three pieces- button side, logo side, and key ring.  The cover snaps together- see below video.  Snapping the cover together takes some force, this is done so that it holds together tight and doesn't pop open if you drop it.  There is a small notch near the key ring where you can use a wide flat head screwdriver to pry it apart.

This should fit most of the modern/current pushbutton start Ford key fobs.  The button opening is extended the full length so it will work with fobs that have buttons for remote start, etc.

There are two options-

• Standard, with smooth sides

• "Stitch", which has geometry that looks like stitching.  The stitch can be printed in a different color to match your vehicle's interior (I did mine in the Maverick Lobo blue/yellow).

These work well when printed in ASA or PCTG.  I have not tried other filaments.

The parts are designed to be printed with a .4 nozzle and .2 layer height.  The cover in the photos/video was printed with fuzzy skin turned on.
