The author remixed this model.
I loved the original model by GreySiD. But I wanted one that didn't require supports, and had a larger internal volume. The original model had 10mm on both sides that were not being utilized, so I hollowed it out. I extended the flanges on the container to extend all the way to the build plate. No Supports needed. I added about a 0.1mm additional tolerance ONLY to the top of the mounting flange to account for minor bridging droop.
