Seven lobes, a 150 degree twist, single wall in vase mode.
Printed in vase mode: one wall, no infill, no seam. Seven lobes turn through 150 degrees over the height, so light falls on it in bands and small layer defects stop reading.
The floor is solid, 2.4 mm. It holds water, but put a glass or a test tube inside anyway: vase mode is a single wall, and given long enough PLA will start weeping along the layers.
Printed on a 0.4 mm nozzle at 0.28 mm layers. Finer layers smooth the lobes a little and double the time; it is not worth it.
1.8 mm wall, 36 flutes, E27 collar moulded in.
True icosahedron, 22 mm across flats, no numerals.
A (3,2) knot, 13 mm section, from the actual parametric curve.

Напечатал на 0,6 сопле слоем 0,4 — доли стали грубее, но для тёмного PLA даже лучше смотрится.
Спасибо за обновление дна, старое подтекало по краю.
