About this part

This is a replacement key fob case for the 2007 Mazda3. Likely works for key fobs made for similar generation vehicles around the same time frame. Use with all internals of fob, this print requires the rubber gasket/buttons. Print "Button Test Plate" to test if button configuration fits.

To Print the Fob

Print two "Button Side Latch", print one of everything else.

Also attached is the Prusa Slicer file with settings I used to print.

PLA. 0.2mm Layers. 100% Infill. Supports with 55 deg overhang threshold. Brim required around latch pieces. Print time 2 hours and change with my settings.

**DO NOT LEAVE IN SUN / HOT CAR / TEA KETTLE IF MADE WITH PLA**
**UNTESTED IN ANY OTHER MATERIAL. PETG COMPATIBLE FILES IN PROGRESS**

The side latches are symmetrical. Just click them in. The front latch has a short latch and a long latch. Orient with long latch on top.

You may need to sand some parts to fit. There is a gap between the top and bottom parts of the case I am working to resolve.
