Sometimes we humans need to build machines with the sole purpose of demonstrating the effects of gravity on a steel sphere. This is a machine that happily fulfills that purpose.   Be mesmerized by the combination of engineering and physics resulting from the simple motion of turning a gear.  Watch as the steel ball bearings gain potential energy as they're being lifted by the big wheel, only to be converted to kinetic energy as they roll around the well and tumble back to the bottom.  Be amazed by the fact that this whole thing is 3D Printed.

This download includes all of the STL files needed to print your own Gravity Well desk sculpture and requires no additional tools for assembly. This piece will bring you some needed meditation reminding you that there is order in the universe after all.

You will need to purchase 1/2" ball bearings (or 12-12.5mm) which can be found here:
https://geni.us/halfinchBallBearings 


Recommended print settings:
Layer Height: 0.2mm (All Parts except Well) | 0.1mm for Well 
Nozzle: 0.4mm

The largest file size is the dish, which is 205mm x 205mm.  All the files have been pre-oriented to save you some set up time. 

The Gravity Well

Base.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.

This video shows the whole assembly process:

The STL File:

Prints on all standard 3d printers, requires the following additional parts:

11 3x10x4 bearings: https://geni.us/ytgU1tC
M3 Screw Kit https://geni.us/CnX30
32 0.5in ball bearings: https://geni.us/uLEbw
Nema 17 Motor https://geni.us/IbL6D0
1 GT2 Pulley https://geni.us/l3MG
You will also need a way to drive the Stepper Motor: 

I recommend this board: https://geni.us/2sH7WYY
Real Time Module (Optional): https://geni.us/rtKYLJT
(Here is a really good tutorial for driving clocks with a stepper motor: https://www.youtube.com/watch?v=PR4PXR7RXEY&t=253s)

Recommended print settings:

Layer Height: 0.2mm

Nozzle: 0.4mm

Infill: 15-18% 

Can print on any standard sized printer.

**All the files have been pre-oriented to save you some set up time! All you need to do is drop the parts into your slicer and hit print!
