I got tired of knocking my chain lubricant bottles onto the ground every time I bumped my PCS-1 bike repair stand. The 104 work tray is great for holding wrenches and other tools that can slot into the holes, but it's terrible for holding tall items like lube bottles. So I designed a tray that clips onto the stand's tube and is held in place by a zip tie. This should work on any repair stand with a 42 mm diameter vertical tube.
