Reloading Koozie

I kept seeing these reloading koozies on the web but no one wanted to share the files or even sell them to me, they just wanted me to pay some outrageous price to buy some cheaply made koozie with breakable tabs and then spend more money for replacement parts. So i used my golf ball picker upper as a reference and after many iterations i came up with what you see here, a reloadable can koozie that is durable, insulated, and has modifiers in the 3mf on the top and bottom to ensure the tabs are tough and wont break. Me and several of my friends have been using them for weeks now and they work great, please reach out if you want modify this or if you have some changes to make it better, but please don't use this commercially or sell them, this is the only design i have ever made and i did it so us poor folk could have a fancy reloading koozie.
