April 28, 2019 Update
Print 3 of the Standoff parts, and 1 of the switchplates. I used superglue to hold the standoffs to the back of the switchplate. Then I used M3 heatset inserts on the bottom of each of the standoffs. Drill through the center console and use M3 screws to secure the switchplate. It will bend slightly to contour to the factory center console.
BELOW THIS LINE IS OUTDATED
THIS IS STILL A WORK IN PROGRESS
I am working on a full drop in switchplate to replace the factory ash tray. For now I have the switchplate designed and fitting well but I need to work on a way to secure it in place. There is also a slight curve to the center console that I didn't account for. Haven't decided how to adjust for that yet.
Print from PETG or ABS. You don't want PLA as it will melt/warp in the hot car.
