Kyudo Arrow Nock 1913 Tube

An arrow nock for kyudo that fits into a 1913 size tube. Printed and tested in PETG. 

Notes (will update after more use):

- supports cause a really ugly surface on my printer, which I don't know if it's normal or just my lack of skill.

- about 4 shots in, there doesn't seem to be any wear on the nock, will keep using it on the makivara arrow and report if it fails

If anyone else prints it and is a more prolific practitioner, or perhaps a novice (as we often rotate the arrow poorly after locking it), let me know if or when it fails. A photo would be great too, so I could improve it, thanks! :)
