Sometimes the pins holding the springs together break due to wear and age. This model is designed to be an easily printable replacement.
You will need to supply your own M2 x 12mm-ish long screw for each pin! ±2mm length should be fine.
The original screw cannot be reused, due to its size and therefore risk of layer delamination.
Print on the flat side, use enough perimeters so that the pin is solid. The handle can be left hollow, it is just designed for ease of holding during installation.
The author marked this model as their own original creation.
