An Improved Broadhead box.
The lid is a friction fit so your tolerances need to be dialed in. DO NOT close the all the way when empty you will not be able to open it again.
EDIT:
I added 2 new lids v2 that have finger cutouts to make it easier to open and to help prevent it being unopenable if closed all the way.
