Solves the problem of needing one more threaded stud in Openbeam, when you've already capped the ends. A BIG time-saver that gets you out of a crunch!
You've finished building your Openbeam masterpiece, then find you need one... more... bracket. UGH. Rather than sighing and taking out the wrench to loosen off and remove 8 bolts so you can insert another nut, use one of these.
This T-Bolt slips into the gap of Openbeam, then twists and locks into place so you can add an attachment with a M3 nut. This part is a LIFESAVER, when the only other option to you is to drill right through your Openbeam to make an attachment (ug!)
