The file 'Human Heart Hi-Fi 3D Printer Model' is (stl,thing) file type, size is 14.9MB.
This is an anatomical human heart.
I printed it using raft and supporto with NinjaFlex filament:
settings: speed 30 mm/s, travel speed 90 mm/s, Temp 225*C, 15% infill, layer 0.2mm. Printed out beautifully.
Should work fine also with PLA, let me know
