This is just a simple print that slips over the cap of you lip balm, or chapstick, to make it into a key chain. its much quicker to grab you chapstick if it's hanging on the side of your bag than buried within the void.
It's a pressure fit, but you could always use a little glue to make sure it stays put. I used a clip I had lying around, but you could always print a carabiner.
The author marked this model as their own original creation.
