The most challenging print in years. Took me three tries. The first two times everything looked great for the first 40 hours. Then things inside started to wobble and led to layer shifts. The way to get it to work was to slow the print down to 65% and put a thick layer of Layerneer Bed Welt on the Prusa satin sheet. Total print time almost three days. It does look good but. It sure it's worth the effort.
