Maelstrom2

This is a modified version of https://www.thingiverse.com/thing:4155838. It is much larger and has 7 ribs per cell instead of 5. It is a challenging print ; if you decide to print it I'd suggest you set your slicer's Z-Lift/Z-Hop parameter to a value of 0.2 - 0.5 mm.

Maelstrom2 printed in 26 1/3 hours using a print speed of 80 mm/sec and a layer height of 0.200 mm.
