Hardware Kit

For Which Marble Machine?

This is a Complete Hardware Kit for our Marble Machines. It will come in handy if you do not want to source the parts yourself. 
While we ship the critical parts, you will 3D print the rest of the product.

Please select the appropriate kit version for the design that you are 3D printing. One includes M3 fasteners and the other doesn't. You need one kit per marble machine.

All our components are plug and play - no electronics knowledge or soldering needed! (Watch the video and at 20 seconds you can see how easy it is to connect the motor)


There are 2 versions of Hardware kits. They come with everything required to assemble the machine for the version that you choose (except for batteries).

The Two Wheeler:

  • 50x (7.144 mm | 9/32 inch) Marbles 
  • 1x   N20 DC 3V 15 RPM Motor
  • 1x   Battery holder
  • 1x   Metal On/Off Switch
  • Super Glue
  • Nuts & Bolts & Allen key 

All Other Marble Machine Designs:

  • Same as above, except for Nuts & Bolts & Allen key 

NOT included in any of the versions are:

  • 2x   AA Batteries

The kit can look slightly different as in pictures. Functionality remains the same. When ordering multiple kits, you might receive fewer superglues due to size constraints inside the box.


There are two locations that we ship hardware kits from.

To the US and Canada, we ship from the USA, Tennessee.
We ship tracked with USPS and delivery times are usually under 1 week.

To the EU and the rest of the world, we ship from Slovenia in the EU, and you have two shipping options:

  • Non-tracked  (around 1 week across EU)
  • Tracked    (a bit less than non-tracked version)

We ship worldwide and we try to ship the next working day!

We however stopped shipping packages to Romania. Almost all get lost so it is just not feasible.

Easy option

THe hardware kit is an easy option if you don't want to shop all items seprerately.
Ans in this case it will always fit and work, no risk order.

Geoffrey C.
Great Hardware kit.

This hardware kit does exactly what it says. Easy to put together, everything worked well first time.

Would be nice to have more difference coloured marbles.

Just simple easy convenient

Simple to use. You don't have to source out and wait for items to come form all over, from different sources and fairly quick. Just have to watch motor rotational orientation as some times you have to flip wires for correct rotation. Takes seconds
