Condiment Inverter
thingiverse
Well... this is simple. The mustard used to have a big flat cap so it could sit upside down ... and be easy to squeeze. They changed that. So I made this. inside diameter of the top is 40mm, Outside diameter of the bottom is 70mm. Very stable. Prints without support. You can probably scale the STL if you don't want to futz with OpenSCAD to make different sizes. On edit, I added the Condiment Inverter. It's larger and has a notch to steady the bottle --- but it can handle salad dressings and ketchup.
