Its the fearsome Dread Gazebo!!! A popular D&D joke that's been around since the 1970's, now for your printing pleasure!
Interested in supporting my efforts making free models for the world to enjoy? Want to access even more models not found here in Thingiverse? Check out my patreon page here: https://www.patreon.com/mz4250
Just print each part separately and enjoy! Oh flip the teeth upside down before you print :-P
