Combine this 3D printed part with a length of 3/16 (5mm) stretch cord to keep your tripod, or other item, in the folded position. Snap the keeper over the leg of the tripod and you're ready to go. I've provided stl files for keepers that should fit over 22, 24, 26, 28, 30, and 32 mm legs. PLA filaments works well and they take 30-45 minutes to print using the .20 mm Strength profile. Tree supports from the bed only provide sufficient support.
