The new and improved clips should be printed in a TPU with several perimeters to reduce wear. The holder can be printed in any hard material (PLA). The holder holds 20 clips for when they are not in use. The clips work with most bobbin holders as they do not protrude out very far. The new handle design allows for easier attachment and removal.
The author remixed this model.
I made the clip handle of my original model more ergonomic by adding an indent to it. I also added some chamfers to the holder allowing it to print cleaner.
