Fibonacci Spiral Clock 30x30

thingiverse

This is a 146% scaled up version of https://www.thingiverse.com/thing:3955834, ideal to be printed on 30x30 bed printers (e.g. CR 10-S), using all available space. When scaling, several details have been accounted for: the thickness of the dial, hour and minutes is enough to keep them rigid despite the increased size; holes are still ready to be mounted on standard quartz clockworks (in fact, minutes is given a non-round shape that should minimize slippage). STLs are provided facing down (the clock visible face is printed against the bed): in my setup I print on a glass bed which gives a nice glossy finish. The models can be flipped is this is not desirable. I printed the dial in white, and minutes and hours in black. I also glued a thin black cardboard behind the dial, to give the numbers adequate contrast.
