Cello/Viola/Violin Bow Nut Cap

Simple cap for adjusting nut on cello, viola, and violin bows. Created in response to a cellist who scratched his instrument with the metal nut on his bow.

Fits most bows with 10mm octagonal adjusting nuts. Cap is 18mm in length with internal opening of 16mm to fit most bows. Can be adjusted in your slicer as needed, or import the STL into your CAD program and adjust (or design a new one).

Snug fit so should not come off during playing, but easy enough to remove if needed. Print with TPU or other flexible filament. Less than 1.25 grams, so should not adversely affect weight or balance of your bow.
