As makers, I think we probably have the following two in common:
1. We like building stuff!
2. We have a 3D printer lying around somewhere.
While often #2 is seen as the perfect solution to #1, Root has some unique characteristics that can substantially increase a printer's usefulness to your project.
So, what is Root?
Root is a building system that consists of 3D-printable "blocks" that clamp around rigid shafting. 3D printed parts are very versatile and inexpensive, but weak - the shafting fixes this.
Root works the same way as a traditional building system like 80/20 extrusion would. Beams of varying lengths and gauges are assembled, and features are added along them: various actuator mounts, joints, linear sliders, sensors, wheels, rotary power transmission, and much more.
Root is useful in that printed parts can be stockpiled (jump right in to a new project, don't wait for your printer) and reused between projects. Also, no need to CAD!

root demo object.step
This is a quick demo object I made to explain some of the concepts of Root.
1×
48mm base
This unit is the base of the whole system. It is 48x48x8, and can mount bearings and screw to other components.
1×
24mm base
This unit is half the size of the 48mm base, but can still screw to other units and can mount bearings.

M6 Nut holder
This piece holds an M6 nut into the center 8mm hole, clamped between two blocks. This facilitates stronger connections between block sets.
1×
90 degree block
This piece clamps to the outer face of a block, and can clamp onto a perpendicular set of beams.

Wooden dowels
Wooden dowels can be used as a cheap shafting alternative.
