Nautilus gears sculpture

Inspired by the mesmerizing slow animations in https://hackaday.io/project/178080-nautilus-sculptures

I could not resist to reworked the great openSCAD design of Parkinbot's involute Herringbone gears 773764

into a huge motorized sculpture of many interacting gears. A set of 8 to 12 gears fills an entire window.

The design is modular, you can rearrange gears as you like. Simple chains, 3-or-4-way-stars, rings or many other weird geometries.

One of the gears should be motorized, the others are driven.

We use a very slow geared motor,

The shaft of the gears are pressfit into the gears. the shaft in the hab should run smooth, with a bit of silicon-grease. Remove any visible seams on the shaft.

The parts need a print bed 21 x 25 cm. (As large as a Prusa I3 MKS3 can do)

Print the gears as lightweighted as possible, very little (adaptive!) infill, only one perimeter.

Print the hubs and connector arms with normal settings. (2 perimeters, and e.g. 20% infill)

The arms feature a battery bay for a 16855 Li-ion cell.

The motor housings feature a press-fit opening for a mini sliding switch, that would be normally back-mounted with two small screws.

The arms and hubs have a precise fit. Beware. Test with a small part first, and apply some inset or under-extrusion, if they do slide into position easily.
