Arrow Nock

thingiverse

I'm still refining my design for an arrow nock with a diameter of 4.2mm. If you'd like to visualize the dimensions more accurately, I've attached a DWG file that can be scaled up or down as needed. Before we move forward, I want to make sure this design is functional in real-world applications. Have any of you had success with similar nocks, or do you have any recommendations for improvement?
