MicroRAX is a miniature light-weight T-Slot style building system. Suitable for use on your desktop or bench top to build science, engineering, or advanced hobby and DIY projects.

The knuckle hinge allows beams to pivot end-to-end with about 90 degrees of rotation. The bushing that connects the joint works with a 3mm OD shaft if you want to run a shaft through several joints.

We are selling these as single joints so you'll need two of these to make a full knuckle (one per side).

• +/- 90 degrees of rotation
• Bushing works with 3mm OD shafting
• Need 2 to build a complete knuckle
