Description
This project involves the 3D printing of a replacement stopper part for a Velux blind (roller/shade). The stopper is the small but essential component located at the bottom of the fabric that holds the cord under tension, ensuring the blind remains properly stretched and functional.
To provide a durable and easy-to-print spare part to replace broken or worn-out original Velux blind cord stoppers, thereby extending the life of the blind without buying a full replacement system.
3D printer (FDM)
Filament: PETG or ASA recommended (for UV and heat resistance near windows)
Small screw or pin (if needed, depending on the cord fastening)
Tools: screwdriver, pliers, utility knife (for old part removal)
File: Veluxe stopper.stl
The part is designed to fit the lower corner of a Velux blind, replacing the original cord retention block.
It has a groove or hole to hold the tension cord, keeping the fabric stretched and aligned.
Compatible with several Velux blind models using a twin-cord tension system.
Compact design to minimize visual impact and interference with blind operation.
Remove the broken original part, if still in place.
Thread the tension cord through the groove or hole in the new printed piece.
Use a knot or clamp to hold the cord in place if needed.
Push or screw the part back into its original position at the base of the blind fabric.
Check tension and alignment before using the blind.
Use weather- and UV-resistant material (PETG, ASA, or similar) to avoid deformation from sun exposure.
Do not overtighten the cord or force the part into place – risk of damaging the fabric or rail.
Keep cords safely out of reach of small children.
