Adhesion Test
thingiverse
This is a single helix I posted on Reddit in r/Ender3 as an adhesion test. I had a few requests so I figured I would post it up and let some people see who can do it best. I also included the sldprt file so if you want you can adjust it and make it your own. If you have any questions, reach out!
