I made a replacement divider for my 4runner center console cubby. There are tracks with a 3 degree angle that are factory - these slide right into those.
Recommend ASA, ABS, or something that can withstand the heat of a car baking in the summer.
Made a tall and short version (there are two tracks in the cubby- a deep one at the bottom, and a shallow one towards the front\charger area).
The author marked this model as their own original creation.
