This is a fully functioning 3D printed grandfather clock.  Using mainly 3D printed parts, this clock was specifically engineered to be assembled in minutes, and can run for over 6 days on a single winding. With a little bit of tuning, it can accurate keep time with that classic tick-tock sound.

The video below shows how easily this clock can be assembled

The 3D Printed Wall Clock

0 Entire Part Layout (For Planning).stl

Is it digital, or is it analog?  Well it's some combination of the two! The rack driven 7 segment display is a fully 3D printed mechanical desk piece that is equal parts satisfying and bewildering.  Turn the top dial to rotate a series of 14 cams which push on a rack and pinion system to reveal a number.  Operate is manually, or add an optional servo motor to the back and have the thing run on it's own.

You could even throw 4 of them side by side to create a clock!  Add another two and get the seconds.  Give one a randomized number generator and it becomes a dice!  Endless possibilities!

Prints on all standard 3d printers, requires no additional tools or assembly, and assembles in seconds.

The Clock

ALL PARTS The Clock.stl

A clock that runs by balancing marbles on a teeter totter!  Once every ten minutes, the top seesaw tips, dropping a ball onto the the 10 minutes track.  Every hour, the 10 minutes track tips, dropping a ball onto the Hour track, and every 12 hours, all the tracks tip, and the clock starts from 1.

I have included the step file to help you with assembly!  Feel free to make mods at your pleasure, however note the files are for personal use only.

The Tipping Marble Clock

Tipping Clock Full Assembly.STEP

This is a pack for Matrixed Marble Machines that adds models and instructions for building three counter modules that can be used to turn your machine into a rolling ball clock. There are models in this pack which can be used to count minutes, tens of minutes, and hours.
Additional materials required to build this model include neodymium magnets, bearings and M3 hardware.
Consult included documentation for an exact bill of materials.

This pack is also part of the [Clock Starter Pack](https://thangs.com/designer/HFoG/collection/Matrixed%20Marble%20Machines%20Clock%20Starter%20Pack-31422).

This is the escapement powered by Bob, the humble escapement operator.  Bob is the one responsible for adding a pulse to keep the pendulum swinging, as well as triggers the advancement of the escapement wheel. This is my take on this escapement designed by dgreene909

The Walking Bob Escapement

Build 3 - 7.5h - 53g.stl

This is one of my all time favourites- instead of a pendulum, this escapement uses a ball bearing rolling along a track to keep time.  At the end of the track, the escapement hits a trigger which causes the track to slant the other way, starting the cycle again.

The video below shows how easily this mechanism can be assembled!
