Toppl Stopper Plug

A coworker of mine approached me and asked me if I could design her a stopper plug for her dog's Toppl enrichments toy. She explained how she was having issues finding affordable stoppers to use to fill and freeze her Toppl's and wanted to see if I could help. This is the design I came up with and im very happy with how it turned out. I made this stopper with a very slight taper to it, allowing the stopper to fit really snug in any Toppl, as they all seemed to have slight variances in hole diameter. This allows for a very tight seal that will not leak! The dog bone shape has been added to make it easier to grip the stopper to pull it out with ease. As a bonus I also included a support ring to sit under the Toppl to hold it steady while it is being filled and frozen. If you like my design, please give me a boost! I hope this design helps your doggo get more enjoyment out of their Toppl *************THE PLUG MUST BE REMOVED BEFORE GIVING THE TOPPL ENRICHEMENT TOY TO YOUR PET!!! I
