I tried all the "fixes" but they don't work properly. With this one, you simply clip it on, push in the broken metal string and bend it with pliers. Good as new!
When you bend the rods, make sure not to break the plastic!
Printed with 0.2 layer height 10% infill.
The author remixed this model.
The original model didn't hold the metal rod at all. My improved version lets you push it through and then bend it, which secures it very well.
