This is the Cone Buddy! A gadget designed to speed up the raw cone packing process. I designed it myself and have been using it for 2 years now with no issues. It was originally designed for King size cones, but I also discovered it works great with their classic 1 ¼" size cones as well. The inner chamber is tapered to fit the cones perfectly to prevent spillage. The handy packer(stick) is used for packing the herb down into the cone to ensure it is tightly packed. 

On the main body the lever is free floating so make sure you enable supports. I recommend enabling tree supports and selecting the “On build plate” only option. Otherwise the supports are a giant pain to remove from around the lever. That being said, be very gentle when removing the supports around the lever. I've only printed this in PLA but have had 0 issues with it. I hope you enjoy it as much as I have!
