Replacement for the bottom hook of LuxaFlex systems.
The first (and cover) photo is what the model looks like, the second photo is the original.
They don't seem to be sold separately (anymore), but they do break quite easily, hence I modeled a replacement.
No special instructions are necessary. I printed them in PLA at 0.20mm with 20% infill, but it probably doesn't really matter. Printed in around 25 minutes.
