Collapsible Arrow Roller
thingiverse
I've made an arrow roller that can be broken down so they can fit into cases. If you don't know an arrow roller can test if the arrow is straight. For the barrings I used a PGN 6201: https://www.google.com/url?sa=i&url=https%3A%2F%2Fpgnbearings.com%2Fproducts%2F6201-2rs&psig=AOvVaw0LqG6rP6Lc1AYaebWTmpl7&ust=1676408245593000&source=images&cd=vfe&ved=0CAsQjhxqFwoTCNCG9sGxk_0CFQAAAAAdAAAAABAD
