Migrated to: https://www.printables.com/model/544957-replacement-lowel-7038-light-stand-set-knobs These are the SMALL set knobs for the Lowel Omni Stand 01-33 (and apparently Uni TO Stand UN-33 and Uni-stand UN-33), to replace the knob-end of Lowel part number 7038. If you need the stud, it's kind of an odd bird. You can cut it from 12-24 all-thread, if such can be found. My studs are barely under 7/8in long in total (and they've apparently been ground at the end).
