There are many simple toothpaste squeezer models out there, but I found them unsuitable for all situations because I could not always fit such squeezers around different tubes due to variations in tube dimensions. In order to remedy this, I made this Fusion360 model where you can quickly customize the important aspects of the model:

Included are two pre-configured models in case you don't want to make your own: One suitable for toothpaste, and another suitable for a CeraVe moisturizer tube (pictured).

Printed in PETG at 0.2 layer height, but anything filament ought to work (except maybe TPU).
