Car Seatback Bag Hooks. Design by YoungBuck.
Made these for my Dad, since he wanted to put garbage somewhere other than under his seat. Printed really well and sturdy.
Warning: In new model trucks, you may want to sand down the bulge so you can attach it easier, as it is really tight. I broke one trying to get it on, so for thinner bars it works well, but if you print in ABS or a more flexible plastic it would work fine.
I separated them and printed it flat on the bed. I think this would make better results. I don't think you need a raft, but I did use a brim since I had issues with curling on other prints, although this one printed perfect everytime.
