Curtain Track Hook, 30mm and 20mm widths

Curtain hooks made to replace old broken ones, they seem to be getting harder to find in shops. I made these to be chunky so less likely to break. Designed in OpenScad, file included, can be adjusted or changed.
They are made 5mm deep to fit a metal track, one 20mm and one 30mm depending on the width of the track. Might need size adjustment for any other type of track. Let me know if you need a different size posting. Or have a go with OpenScad and the file included, its open source :)
