If you haven't seen these, I think they are pretty slick. They are a 3d printed black bezel that takes a Double DIN stereo and puts it in the factory dash.
I just finished up the install and thought I would share. The bezel fits tight on my Pioneer head unit. The Bezel had several pre drilled holes in the side of which one pair perfectly lined up on the unit. Mounting to the bezel was easy. I mounted the stereo to the bezel first and then slid them into the dash as one unit.
The dash does have to be cut and you lose the ashtray but cutting is easy with an oscillating multi tool. I do wish they had included a template as I initially cut to low towards the console. The sides are easy enough to sneak up on but I cut out the entire section. As I was fitting it, I learned that it actually slides over the lowest portion of the dash. The new dash cover fixed my goof and hopefully I can save someone the trouble. It probably wouldn't have been noticeable when installed unless you were laying on the floor, but there is about 3/4 to 1 inch of the lowest part of the dash that is visible when done right.
Mounting the bezel into the dash was a matter of predrilling the holes and using a pointed tip screw. It thread into the plastic core the dash solidly. The lower screws you can reach behind and add nuts and or washers as needed in the void where the ash tray was. Had I not cut too much, there would have been plastic core there as well to accept screws.
Here are some pics.
It does look crooked do to the curvature of the upper dash but it is perfectly parallel to the console and map pocket.
Still have a few things to finish up on the inside but won't button that up until I get the blower issue resolved.
