These broom holders wear out over time and need replacing, but, to the best of my knowledge, there are none. This model replaces the broken part and makes the original product usable again.
I will add the file for the harder tpu later, which will have notches for easier bending.
I used TPU 95A, which is pretty hard. I would recommend something softer, like 85A: Amazon
currently the price is about $26. It should be hard enough to run on not just direct drive extruders, but on bowden as well.
This is the product the gripper replaces, but it fits others too: Amazon
The author marked this model as their own original creation.
