Tapered Stopper

thingiverse

I snapped the cap off my glue bottle. I recalled this gadget based on a product called "Twist-n-Seal." However, it would take longer to purchase than to print - so here is my version. Use your slicer to expand or shrink (using "scale") to the precise size you need - two versions are shown in the photo from the same STL file. I created mine in TPU and the flex filament version works perfectly but I believe a solid version would also work well. UPDATE 1 - If you print in flex filament like TPU, I suggest 100% fill - not for compressive strength but for tensile strength - My original glue stopper broke after multiple pulls out of the container (it was only 30% filled).
