shorter gooseneck and weight test:
i shortened the gooseneck vertical pieces about 4mm, this picks the front end up a bit. new material is pla plus, thicker layer size and less infill. i don't like it as much as regular pla
also realized that the horizontal pieces need to be longer, or that flip over tongue needs to be designed
ok here's the weight test, this bucket is 14 pounds, flattened the trailer right to the ground..
here's a couple shots with starbuck's bottles, each one is 14 oz i think, still pretty close with all in the center
here they are spread out, didn't help much
here's why there's so much flex, there's no longitudinal stiffeners other than the outside L shape aluminum
