Isopropyl Alcohol Fill Helper

thingiverse

This is my go-to "Isopropyl Alcohol Fill Helper" for 5 liters containers made by "Dienes". I prefer to manage my Isopropanol in small 1 liter bottles. However, filling the bottle with a Ø20mm opening from the 5 liter container is always a hassle. The fill helper is designed in 2 steps to allow for precise alignment of the funnel and screw lid after the gasket has been inserted into the screw and screwed onto the container. Various gasket materials have different thicknesses, so I used a circular cutter to create Ø30 mm and Ø41 mm circles with the same center. A sheet of 1,5 mm EPDM serves as my chosen gasket material, which is attached by friction to the screw lid. To secure it in place, I rely on a superglue, also known as Cyanoacrylate adhesives. I'm well aware that I could easily purchase this tool elsewhere. But why bother when I have a 3D printer at my disposal?
