3 individual tree/plant models for architecture projects optimized for 5 different scales, print-in-place. Use freely in your 3D printing projects under CC BY-NC-ND license, do not sell, use attribution for citylab.lv if re-publishing.

(!) Print with the settings below. A small inaccuracy can lead to a failed print when printing trees and plants with overhangs. So most importantly - print with low speeds (but not too low), including travel, and minimize warping on overhangs, so keep cold air away from the print. Keep bed temp a little higher for some material softness if the trees have trunks, so it can bend a little without breaking. Use 0% infill and no supports. Tested on BambuLab P1S with old and brittle PLA filament to be sure that the models and settings are as fail-proof as possible. (!) Changing scale not recommended (!) Tested only on Core-XY printers (bedslingers not recommended)
