For extra load capacity, I added backing plates that use either #6 or #8 screw. For those you want to hang helmets.

I made adjustments to the inner fillets of the hook, hopefully this will help with some of the fitment issues. I also uploaded a looser fitting backing plate(lower tolerance) if needed.

This cap hook is designed for those who have multiple caps and need additional storage. With this hook, you can neatly store multiple caps and have easy access to each of them.
The hook is designed for, and works best with, caps with an open back and have a clasp. Like the below image.

To remove the hook, PRESS the button on the side, then slide the hook upwards.

THIS HOOK REQUIRES SUPPORTS, I have uploaded a couple different models, one with supports built-in (must be printed at .20MM layer height) and one without. If you are comfortable with your own supports, I recommend you print your own.
