Stop your outdoor Xfinity/Comcast box from swinging open! The "mystery threads" on these utility boxes are actually a standard F81 coaxial barrel connector (3/8-32 UNS thread). Standard hardware store nuts will strip it instantly. This custom-tuned remix fixes it perfectly. Click over to the model page for the exact 0.08mm layer height print settings and OpenSCAD parameters to get a smooth, weather-tight fit!

Remixed to actually hold Japanese knives without slippage — the original even noted drift with heavier German blades. Upgraded to 6x 18x3mm magnets for a rock-solid hold. Added a personalized text unit (mine shows 黒染 for my Kurozome Damascus Bunka). Two-color print in white and red marble for contrast. Mounts with removable 3M Command strips — paint-safe removal tested. Full description on the model page.
