Hello math teachers! 

Do you need an interesting hall pass for your classroom? 

Look no further. This is a Sigma symbol that your students can use as a hall pass. Big enough to not get stolen, and durable enough not to snap in half right away.

.3mf file is customizable to allow specific last name to be inserted, just simply edit the text field in Bambu Studio. Or for those on Bambu Handy moble app, you can select the generic hall pass without any text. Entirely up to you!
