Printed perfectly in PLA. Tested it on a set of goalie sticks just to see if it would work and though there were no issues staying or putting on, I would love to know the best percentage to make it a little bigger so I don't feel like I'm going to break it. For a standard set of sticks, these are perfect! For even more durability, consider PETG! Thank you so much for sharing this. As soon as I get a boost token, consider this boosted!!!
