Luxaflex stopper for horziontal blinds (25mm)

thingiverse

This is a stopper/brake for the robes of 25mm horizontal blind made by Luxaflex around the year 2010. I already had to replace the stoppers before because they are designed to light for their use. Especially when you have larger surface (higher/wider) blinds. (mine are about 210 by 210 cm). At that time I had to go through a large collection of 2nd hand-items at a local dealer to find them. But even there most of them had already light cracks in them. When there is a crack the effect will be that the stopper does no longer hold the blind up fully. They slowly slide down a bit up to the point that it doesnt work at all. Luxaflex said it might be the robes and I could not replace that myself so they had to be brought in for reapair... Dont think so... (The last photo shows the original item)
