Blind and Shutter Replacement Parts

Why is a single blind clip impossible to buy?

Clips cost pennies to mould and are sold as part of a complete headrail kit. When the range is discontinued the individual parts disappear, leaving a working blind with one broken hanger.

It is one of the clearest cases for printing that we see. The blind is fine. The fabric is fine. One small plastic hanger has gone brittle in years of sunlight and snapped, the slat is on the floor, and the only thing anyone will sell you is a whole new blind.

Unlike window handles — where a universal replacement genuinely is the better answer and costs under a tenner — blind parts have no universal equivalent. Every manufacturer’s slot profile is slightly different.

Which blind and shutter parts print well?

Vertical blind slat hangers and carriers, roller blind end caps and side brackets, shutter hinges and louvre pins, pelmet clips, cord guides and chain connectors.

The list of what we see:

• Vertical blind hangers and carriers — the hooked clip that holds each slat, and the carrier that runs in the headrail
• Roller blind end caps and side brackets — the moulding at each end of the tube and the bracket it sits in
• Chain connectors and cord guides
• Venetian ladder holders and bottom rail end caps
• Shutter louvre pins and tilt rod staples
• Pelmet and valance clips, which are nearly always discontinued

What they have in common: small, light duty, model specific and entirely unobtainable. Exactly the shape of job printing is for.

Will a printed clip take the weight?

Yes, when printed the right way up. A slat hangs in a straight pull, so we orient the clip so that load runs along the layers rather than across them, where the bond is weaker.

This is the whole trick with clips, and it is why a printed one often outlasts the original. The part that failed was brittle after a decade of UV. PETG starts tougher and the orientation puts the strength where the load is.

The PETG against PLA guide explains why material choice matters here: a blind clip in PLA, baked by a sunny window, will fail the same way the original did.

How many should I order?

All of them. Every clip on the blind is the same age and has had the same sun, so the one that broke is the first of several. Extra copies cost a fraction of the first.

The drawing work is the expensive part and it is a one-off. A full set of hangers is nothing like the price of one multiplied out, and it saves doing this again in six months.

What should I send you?

An intact clip from the same blind, if you can spare one. Otherwise the broken pieces plus photos of the headrail slot and a slat, with a steel rule in shot for scale.

An intact example is ideal because the slot profile is the one dimension that has to be right, and it is awkward to measure from a photograph. We copy it and post your original back with the new ones.

There is more on sending photographs instead in the no CAD file guide.

Will the printed clip match the colour?

Not exactly. We print in black as standard, which is unobtrusive against most headrails. Original white clips have usually yellowed anyway, so an exact match was never available.

In practice the clip sits inside the headrail or behind the slat and is barely visible once fitted. It is one of the places where finish genuinely does not matter.
