Note on Rigidity: My original tests were flawed in this video, and I have since cut them out) as I was past the product's intended bearing stops. At full extension you should only experience 2-3mm of sag in either axis, NOT 10mm as originally (incorrectly) tested. For comparison, 3xMisumi SAR330's have 10mm * of sag at full stroke length.

⤵️ Why Watch?
Offset Robotics has introduced a pre-made 2-stage telescoping tube elevator kit, sometimes called a Box Tube or Telescoping linear slide/lift. To the best of my knowledge, at the time of recording it is the only commercially available telescopic elevator under 40cm long on the market. In this video, I give you a complete breakdown of the 300mm kit, and we'll put it through its paces. I'll share my honest thoughts on the good and the bad, from its innovative design to the potential drawbacks you need to know about. Finally, we'll discuss exactly who this elevator is for, helping you decide if it's a worthwhile investment for your robotics team or personal project.

Full CAD of the kit available on the product page.

Note: The kit was provided to me for review. As always, my thoughts and opinions are my own and I aim to provide you with the knowledge & data needed to make your own informed decisions on if this kit is right for you.
