Robert,
I don't have any pics of the dipper but I have made them two ways:
1) Heat a strip of acrylic by flipping it over and back with the heat source aimed at the point you wish to bend the sheet. After heating it slowly the sheet will start to deform and bend due to gravity. At that point, one can quickly bend the end back on itself, remove the heat and let it solidify again in the new position. The same thing can be done on the other end to make a hook for a handle.
2) I just cut several small pieces of acrylic and glue them together in sort of a U-shape at the bottom and I glue a crosspiece at the top for a handle.
I prefer the second method. I've also seen some dippers with sort of a double prong that was probably routed out and then heated and bent to form the hook.
