I have enlarged, cut and added an alignment peg for the Head of David (https://www.myminifactory.com/object/3d-print-head-of-michelangelo-s-david-52645)
This should just fit on a 235x235x270 printer. Print a 20x20x20 calibration cube first to test your printer and then use the cube to align the 2 halves for gluing.
The author remixed this model.
