This panel was made to hold the Allen Key set for my CNC, but I'm sure it could serve all sorts of alternate uses. Simply two holes 6.5mm in diameter.

What are Polypanels?

"Welcome to the world of Polypanels, a system of snap together parts that let you build whatever you want! It’s like an open-ended construction toy for making functional things, harnessing the power of 3D printing and the community to make it truly limitless."

Intro to Polypanels

Printing Guidelines

A high wall thickness of 5 shells/perimiters will ensure solid snap connectors. From there settings can vary based on your desired outcome. Print solid for the most robust and long lasting joints, or print a lower infill with 0 top and bottom layer thickness for a cool exposed infill pattern.
