I'm trying to fold a relatively simple (?) fencer. To my surprise I couldn't find anything online, so I figured I could make my own model. Here's a sketch of what I thought of — the creases aren't really representative:

Needless to say, developing a pattern didn't go as easily as I thought.

I also have no idea how to extend the arm part to build one from it.

Could anyone help me out?
