Window blind tilt wand clip
The small plastic hook that connects a venetian blind tilt wand to the headrail is often the first thing to break, leaving the slats stuck. The clip is a 25 mm piece with an 8 mm loop that snaps onto the tilt mechanism pin and a 6 mm socket that accepts the wand end, joined by a 3 mm neck with a fillet to spread stress. Print it on its side so the loop is strongest against pull, in PETG or nylon for the flexibility the snap needs.
Blind mechanisms differ in pin size and wand diameter, and SpeakCAD builds the clip to the ones you measure rather than a guess. Ask for a tighter loop or a longer neck and regenerate on the spot. Trying it is free in your browser and there is nothing to install.
Design a venetian blind tilt wand clip 25 mm long: an 8 mm inner diameter snap loop with a 3 mm opening at the top, a 3 mm thick neck, and a 6.2 mm socket 10 mm deep at the bottom, with fillets at every junction.
