Flex-Fin Door Edge Pinch Guard
A C-shaped guard that pushes onto the edge of an interior door. Its hollow 22 mm spacer block hits the jamb before the door can shut, so it can't pinch fingers or slam, and it holds a pet gap open. Four 1.7 mm flex fins inside the 43 mm jaw grip door leaves from 34 to 41 mm thick (1-3/8 in and 1-5/8 in doors) without screws. The part is 54 x 47 x 30 mm.
Light Switch Keep-On Toggle Guard
A screw-on hood that fits over a standard US single-toggle wall plate and keeps the switch from being flipped by accident. Use it on a freezer outlet, sump pump, bath fan or smart-bulb circuit. The 40 x 96 mm base has two slots that fit the plate's 6-32 screw holes at any spacing from 57 to 64 mm (2-3/8 in is the usual 60.3 mm). Fit it with two longer 6-32 screws (about 1 in). The 21 x 35 x 18 mm enclosed hood covers the toggle.
Print-In-Place Shade Chain Loop Tensioner
This print-in-place tensioner for roller and cellular shades has a 40 mm V-groove pulley (8 mm wide, 4 mm deep). The pulley turns on a 9 mm pin and is held in place by an overhead bridge, with 0.5 mm clearance on every mating face. Two #6 screws (4.5 mm holes) hold it to the frame: one goes through the hollow pin and one through the tab. It keeps a loose bead-chain or cord loop (up to about 5 mm) taut and close to the wall, so a worn clutch is less likely to let the shade droop and children can't pull the loop out.
Twin-Horn Blind Cord Safety Cleat
A 80 x 16 x 12 mm twin-horn cleat that screws beside a window frame with two #6 wood screws (4.5 mm clearance holes with counterbored heads), so looped blind and curtain cords can be wound up out of a child's reach. It replaces the small stamped cleats that go missing or snap. Each horn leaves a 6 mm tapered gap for the cord to wrap into.
Print-In-Place Window Restrictor Stay
A print-in-place sliding restrictor stay that limits how far a window sash or door can open: a 136 x 28 x 8 mm slotted arm with a captive Ø10 mm sliding post trapped in an internal T-slot at 0.4 mm clearance, giving 85 mm of travel (screw spacing 58 mm closed, 101 mm at the hard stop). Both mount holes are 4.5 mm for a #8 wood screw or M4, and an integral 1.8 mm leaf-spring detent snaps over the flange near the end of the slot so the window is held at the restricted opening instead of drifting shut.
