Just testing a new filament: Grilon 3 - PLA Z (for better overhands).
I've used Tree supports at 60º. And it came out great.
Printed at 400% size and I've initially started at 80mm/sec but at half the print I had to slow down at 60 mm/sec. Pretty decen print, although quite hard to remove the supports without damaging the print.
NOTE: the "boots" are hollow, which compromises the print integrity. It's a great design, but maybe more suitable for resine printers.
All-in-all, a great result.
Total print time: 26 hours
