Uses about a third less filament. Still strong and completely useful, plus you can see what's inside better.
The pictured model was printed with a 0.6 mm nozzle with 0.3 mm height. So it's a really easy print.
Use supports on build plate only. There is some bridging (1 cm bridges), so maybe PETG or other filaments that are prone to failing bridges might not be a good idea.
The author remixed this model.
