More ergonomic grip for the standard needle collets commonly used in microscopy (see photo). In the .scad file you can adjust the bore to account for tolerances (original holder is 5 mm in diameter). In the provided .stl this is set to 5.5 mm, which works well for me with PLA. It takes a bit of force to push in the metal grip, but still allows removal.
Minor changes from the original design: now all hollow, slightly improved printability and cooler endcap.
