I adjusted the tolerances of the original model as well as tweaked some thicknesses in order to improve the printability on the .3mm setting. Tolerances were previously: 4.6mm model thickness, 5 mm slots, .4mm gap between “wells". Tolerances are now: 4.8mm model thickeness, 5mm slots, .2mm gap between "wells. Prints well in PETG, 4hrs for all 12 pieces.
The author remixed this model.
