This half square Polypanel has one set of snap connectors flipped so panels on either side have reversed orientations. What will you do with such immense power?!
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."
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.
This download contains many variations, including two part versions for printing with dual extruders or multiple processes. Combine the _"Edge.stl" and one of the _"Inner.stl" files.
