Found the original design, but needed large quantity in short order with non-screw option. Found 0.2mm speed in mk3s+ triple 25m, dual 18m, single 11m. Normally print entire bed full without issue. Use cheap hairspray for adhesion. Default print settings for 0.2mm SPEED, Prusament PLA, 20% infill using prususlicer 2.5.0.
For addition time and minimal weight saving one can reduce the height in the slicer by pushing into the bed - sinking (not percent reduction) just until the bottom disappears. (fourth model)
The author remixed this model.
