This is a mod of https://www.printables.com/@greluc_978921 bin. I added a nice snug grip to the antislip damper. It fits right up against the frame and under the motor. slide printer fwd or back just enough to slip it in. (ThatsWSS!)
The author remixed this model.
The anti slip damper was keeping the bin from an up close and tight fit. I just notched it out a bit.
