Tube End Caps

I've downloaded a lot of end cap designs, but I like mine best. It fits snug and is easy to install and remove.

This design is in Fusion 360. It is resizeable if you know Fusion 360. I tried doing it in OpenSCAD but couldn't do the fillets. So Fusion 360 may seem overkill for something so simple, but I found it easier to use.

The size I've uploaded is 26.8mm inside diameter to fit FoodSaver rolls. The bottom is designed to be flush with the outside of the tube. The top has a 3mm lip for easy removal.
