The FG085 function generator kit comes without a case. I wanted something simple and didn't want to worry about fasteners. This is a 1/2 case that slides onto the FG085 from above and below. I cut a piece of gorilla black tape to seal the two pieces with a faux leather effect. The design doesn't include the hole required for the power plug. I drilled mine and then cut the tape where it went over the drilled hole. The hole has to be big enough to accommodate the metal barrel of the power plug and the plastic part as well, or the plug will not reach in far enough to connect.The corners have a tendency to warp away from the glass when printing so I added corner rafts to the design that can be cut away after printing.
