Generated with Meshy using the prompt, "A full trash bag, tied up at the top," and selecting the “cartoon” style. Then I just sliced off the bottoms so they'd be flat and able to stand upright.
The default size of these are not to scale with the toy trucks and cans we have, but they are the perfect size for the augers in our Bruder truck. We can dump them into the top and then crank the augers to move them back to the compactor.
I enabled the Make overhangs printable setting in OrcaSlicer and printed without supports. I haven't tried scaling them up or down, but I don't think you'd run into any issues.
