My neice loves snow leopards and books, so as her birthday is comng up I thought I would combine the two loves and make her these bookends as a present. I have printed two, one in black PLA and one in white PETG, both mediums print fine. I have used generic supports as the tree style support seems to fail in the head area. Also have used 4 wall loops, 50% sparse infill in rectilinear and solid infill as gyroid to increase strength of the model. Works well when scaling.
