This is a replacement fixing bracket for a "vintage" Harrison Drape Supertrack track.
I found models for other similar clips, but none that fit te dimensions of this one, which goes as last bracket at each end and provides longer length to the wall so I designed this.

I used PLA, as I needed a quick print and replacement and did not have PETG at the time.
This is not recommended as PLA is known to deform under weight. So if your curtains are on the heavier side (like mine) it is likely not to last a summer.
I think that I will test how long it will last, before printing it in PETG or ASA / ABS.

You will need to transfer the locking screw from your old clip or obtain a suitable replacement.

NOTE: If you have a similar curtain track and are looking for replacement parts, you should look at my other models.
