This is a simple loop that will snap into polypanels that are compatible with the Polypanel Face-Snap System. It uses the standard sized connector so it will snap into a square, a rhombus, a root-two rhombus, a rectangle, a pentagon, or any other shape that has the standard-sized receiving ring.
You can use this loop to hang up your polypanel designs with a piece of string, etc. It has a lip around the base so that it can't pass completely through the receiving ring. This provides a bit of extra support over what the connector already provides for heavier constructions.
This is a remix of the "Ppfss Template Disc With Lip Standard" (stl or f3D) file included in the Polypanel Face-Snap System.
