This is a simple Totoro-themed toothpaste squeezer.
The opening is 60.62mm wide. The model is 117mm wide, 70mm tall, and 4.5mm deep.
Add a couple extra walls to print the design faster (and for added rigidity).
This is based the opening in this model: https://www.thingiverse.com/thing:49263 by user @makeplace
