Truck bed fishing rod holder

thingiverse

Some pieces I designed to make a rod holder for the back of my truck. They might take a little fine tuning to get the clearances for the bolts to work on your printer but on my ender 3 they printed out perfectly. I was able to print this with support only from the build plate but YMMV. As far as other parts needed I used 1"x1" angle aluminum for the bar that goes across the bed of the truck. You can print as many of the rod holders as you want to attach to the bar, each one uses a 3/16" hex bolt and nut (plus some blue loctite) and 4 1/4 20 bolts and nuts. I have the whole thing clamped down by c-clamps to the bed rails but you could bolt it down too if you're not afraid of drilling holes in your truck.
