Car Headrest Hook for Grocery Bags

A hook for holding grocery bags upright in your trunk. Provided in 6 different lengths and 4 seatback depths for cars with different trunk depths.

Choosing a length

To determine the length required for your car, grab a grocery bag, throw somethings in it and then push it against the rear seats in your trunk.

1. Measure from the top of the handles to the top of the seat back. This is the "height". Round down to the nearest provided size: 30mm, 50mm, 70mm, 90mm, 110mm, 130mm.

2. Measure from the front (nearest the front of the car) side of the headrest posts to the back of the seatback. This is the "depth". Round up to the nearest size: 50mm, 60mm, 70mm or 80mm.

The file names are Height x Depth.

Print Settings

Material: I recommend PETG, ASA, ABS or Nylon.
Settings: Print on its side. Most settings and nozzles will work fine here, just make it all walls and use support for the overhang. I used a 0.8mm nozzle with 0.4mm layer height and tree supports.
