This is inspired by Double D’s Archery arrow puller. I printed it out of PETG for some added strength and added some foam inserts to grab hold of the arrow. I use it on my 4mil and 6.5 mil arrows but it should work with any size. Note: it does require some sort of foam insert to grab the arrow properly. I used some dense black foam from floor pads. I am working on some inserts that can be printed with TPU and should be able to grip the arrow as well.

For the pin in the joint, it’s just long enough to reach both sides with a little excess and then I soldered it to the outer part of the hinge so it does not come apart.
