About this 3D model
The long side of this rectangular polypanel matches the length of the hypotenuse of the right-angled isosceles triangle polypanel created by Devin Montes. This allows you to make wedge-shaped objects (see pictures). I've created three variants: A plain filled rectangle (stl and Fusion 360 f3D formats). A rectangle with receiving ring for compatibility with the Polypanel Face-Snap system. Another rectangle with a receiving ring but with a more hollow design that allows you to see through it.
