Which already was a remix… :) Kudo's for creating the original scad file to p. cornelissen, I merely adapted it (and added some English comments).
Extra features/stuff I added:
You can manipulate the scad file. Do check the various extrusions though when changing the parameters.
Maximum size for a mk3s build plate is 4 columns of 7 cups, or 6 columns of 4/5 cups.
The author remixed this model.
