This is a 3D printed clock a designed off of a concept I saw on posted on Reddit by redditor Phatricko. It uses a high torque clock movement but everything else was printed on a Makegear M2.

Printed in PLA, the print was paused when it got to the numbers layer and the filament changed to get the black numbers.

The hour dial is press fit on while the minutes hand is held on with a dial nut from the clock movement. The second hand was printed then the tiny shaft was heated with a lighter and pressed onto the clock second shaft. It stayed on for awhile before it popped off so I then used the smallest dab of superglue to secure it to the second shaft and it's been on there ever since. Be careful if you try this though, to much glue will bind up the whole clock it you get it in the tube for the second hand shaft.
