Added #8 drywall screw threads to spacer. Hex fits the slim stamped steel wrench that came with my Creality Printer. Flange is 19mm diameter. Overall height is 100mm.
Used this as an alternative to buying hanger bolts (wood screw on one end, bolt threads on the other) to hang a lightweight room divider curtain track from logs. Used slicer to cut to desired total Z height. Spacer tightens down to hold track from lifting up (same function as a nut on a hanger bolt).
Update: Added Torx deck screw version.
The author remixed this model.
