MicroRax - Small Kit

Replacement: None. We are no longer carrying this MicroRax kit in our catalog. This page is for reference only.

If you're in the market for a rigid prototyping system, MicroRAX may be just what you're looking for! 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.

MicroRAX works the same way as other slotted framing systems that you may already be familiar with. Ten millimeter square beams of high strength extruded aluminum can be joined by bolting through joining plates into nuts that fit into the slotted channels. By using different combinations of joining plates you can make just about any configuration you can think of. Bolts are easy to insert and remove by using the included hex key or your favorite 2.5mm hex driver.

This small kit includes enough of the MicroRAX system to do some small projects and give you an idea of what can be done with the system.

    I would like to buy some of these but the prices are ridiculous to say the least.

    Any chance of getting just the 300mm beams? I would rather be able to cut my own lengths and buy the brackets separately, instead of paying for a bunch of smaller pieces that I probably won't use.

    So are these essentially the exact same thing as the Maker Beam?

    Very nice build quality. The small kit has plenty of pieces for me to do a couple of projects. I'm not sure about the best way to mount circuitry or perf boards, though. Any recommendations on how to attach components? The screws/plates that come with the microrax set are a bit bigger than many of the mounting holes on boards I have..

    Photo Interrupter GP1A57HRJ to mount on a MicroRax beam profile. This is a direct re-make of the SparkFun board which can be found here: http://www.sparkfun.com/products/9322

    Microrax wiki I started. Gives some useful information on compatible parts (eg: 3mm shafts, etc...) and kit contents and part information.
