Clock Hands (Gear style) for mini clockwork

Suggested settings:

layer height: 0.1

perimeter: only (more then object width) and/or

infill: 100%

speed reduction to 30% at 0.9 height

filament: PETG for better fitting tolerance

Good to know:

The second clock hand sleeves outside diameters fitting is tight to make the wall width as strong as possible. Grinding probably needed to make it fit. if the clock does not move, this is most likely the reason. 

The second clock hand is not perfectly balanced, which might increase the batteries consumption. Improvements coming soon. 

You can support me by liking or downloading the project and induce me adding improvements. Any suggestions are welcome. Cheers <3
