Using 3-D slicing software, I have created a template for making a cardboard replica from the 3-D model of a mastodon molar that belonged to Benjamin Franklin and recovered from Franklin Court in Philadelphia’s Independence National Historical Park. You can view the 3-D model here and even download and 3-D print if you have a 3-D printer: https://skfb.ly/XGAE. But, if you don’t have a 3-D printer, you can download these plans and make a 3-D replica out of cardboard.
I recommend starting in the middle and working your way outward. Right click on each image to download each page of the plans. If you print two sheets on a page, that will get you close to the size of the original tooth.
