The file 'Retainer/Invisalign Removal Key 3D Printer Model' is (stl) file type, size is 84.4KB.
I was only given one removal key for my invisalign and decided to make myself some backups - note that these are porous unless sealed with a food grade epoxy. The print includes several different configurations, they're fairly small and print quite quickly.
