I created this for my brother - he's a big Leafs fan. It's based on the model I found here: https://grabcad.com/library/wave-or-ola-or-mexican-wave-or-la-ola-1

Basically, I sliced out all but 2 characters using FreeCAD. I used stiff wire and sewing pins to connect the pieces. I fashioned a U-shaped wire that connects the base that the characters sit on to the arms. The wire has a loop at the top that via a pin, links the arms. I had to sand off the little knob on the base (the holes were too small & broke). I glued a semi-circle shaped piece as a replacement for the knob. See view from the back. The Mrs. helped with front & back decals.

Enjoy.
