Gear clock

Sooo where do I begin :) I wanted to make something new, unlike anything before, so I chose gears with two diameters one rolling inside other. I had the idea of gravity pulling the smaller gear down as it goes but this proved very unreliable whatever I tried - giving it more infill, hanging somethin off the gear etc. In the end I had to constrain the movement using two side gears and the small gear couldn't be hanged, it had to be mounted on the backplate.

Features

• uses 56x56x16 quartz clock mechanism (I bought mine here)
• snap-in fit for the mechanism
• no supports needed
• nice design, any color combination possible (I used Filamentum's Wizard's Woodoo to get that amazing glittery flashy blue-purple finish)
• hangable
• read from top to bottom so in the gif the clock starts at 12:00 and make its way to 12:15, 12:30 and so on, you get the idea.

Bill of Materials

• 1x Backplate
• 1x Hours
• 1x Minutes
• 1x Gear backplate flat
• 1x Clock gear (if your clock mechanism have thread choose w thread version)
• 3x Gear backplate
• 3x Small gear

Installation

Installation is pretty easy:

• Screw in all small gears through backplate, in the top use flat gear backplate as you can see on 7th picture. On the bottom you need to install minutes gear along with gear backplate. Make sure the gears move freely, you don't need to tighten all the way.
• Press in clock mechanism, it is a snap fit and on the front push-fit clock gear on minute ring of the mechanism
• All you need to do now is to install hours gear, slide it under minutes gear and tuck over gear on top. Make sure you can backdrive the clock mechanism by rotating the pointy gear in front. Rotate through every hour to make sure it doesn't bind anywhere. You're done!
  

Dimensions

Overall dimensions of the whole clock is 200x200x30 mm

UPDATE (7.11. 2022) - Improved Backplate for more stability and Minutes model for less chance of clock getting stuck
