Cup Holder Table

It's a table. You can eat food while parked, without having to hold everything in your lap.

This should be obvious but DON'T USE THIS WHILE DRIVING. It completely blocks your ability to steer properly, and you'd look super dumb to the police officer having a TABLE in your car if you got pulled over with this inside. Just use it while you're parked like at the drive-in theater, or to go get tacos 30 minutes from your house so that you can eat them before they get cold.

Notes:

I designed this to match my cup holder's dimensions perfectly, so your results may vary. You will need to measure your own cup holder (top and bottom diameters) to make this fit, otherwise it won't be stable enough. Mine doesn't wobble even with some weight on it. If you just print mine without modifying the cup holder file, I doubt it will fit your car and will just wobble around.

A fast way to get measurements is to modify the file (such as in Blender) to remove the top polygons and create a hollow, thin cup - this is what I did. Print multiple cups, adjusting the diameters until you've found the perfect fit for your cup holder. The better the test print fits, the less the final product will wobble. I printed 6 test cups after taking my first measurements, and each took under 2 hours to print. My son was confused why I kept giving him plastic cups. Use a PVC pipe to connect the table to the cup holder. My files are sized for standard 1" PVC (it's actually like 1.05" when measured), but you might want to print a tiny test (just the hole part) to make sure it'll fit your PVC pipe before making the final version.

The tray I used is IKEA's TILLGÅNG, but you can use any tray you'd like ( https://www.ikea.com/us/en/p/tillgang-tray-gray-10419950/ ). To attach the tray, I used Gorilla Glue 5-min epoxy. Sand both the bottom of the tray and the attachment piece before gluing for a stronger bond.

The spray color I used for the PVC is Gloss Black. Whatever color you choose, I recommend gloss. Don't do gray or it'll just look even more like PVC.

I printed at 50% infill, and I wouldn't go much lower. Although it's perfectly stable at 10% it might not be heavy enough. You want a bit of weight so it can counter-balance the food on top. Also I printed 0.3 resolution, and it works and looks fine. I also recommend using 3 walls for added support to the pipe.
