I added a 25mm base in Cura from https://www.thingiverse.com/thing:1905688. I reduced the allosaurus to 17mm wide, and printed it 30deg off from upside down with tree supports. It had to be upside down because Cura stops the supports 4-5 layers early making the front claws completely unsupported and the arms would fail. Inferred I had a similar problem with the add base being unsupported, tilting 30 deg from the vertical allowed the base to be completed and partially self-supporting.

Printed with a brim, 0.2mm nozzle, 20mm/s speed, 3mm/s jerk. Took about 7.5 hours, and Cura says 6g/2.12m of PLA.
