Toy Dump Truck Convoy

The Tiny Toy Dump Truck by madscifi makes a fine tchotchke for a presentation, serving to illustrate the risks and rewards of printing flat overhangs without support. A fleet of six printed well, after repairing some failures as those tall, tall rings and posts near the dump bed pivot fell over. I pasted them down in mid-print using ABS slurry, which is not a technique to emulate.

A closer look shows the overhang problem in the dump bed and the broken pillars behind the wheels.

It’s in monochrome because the camera choked on that much Safety Orange filament in the image, to the extent that no amount of color correction produced a usable result.
