About this 3D model

Fed up with the silicon RTV curing inside the tube of gasket maker due to flimsy caps that crack or split, I deigned my own. This is designed to fit standard tubes of silicone RTV gasket maker that you can get literally anywhere. The walls are thicker and there is a nipple that sticks down into the tube to help create a better seal. Print a few - they're small - that way you always have one on hand when you need it.
