This is a printable faceplate for the temperature regulator and two switches that make up the Filastruder v1 controls. It is designed to be screwed onto the base board.Make sure to flip the model so that it is facedown in your printing program. You want it to be sturdy, so use an appropriate infill (50% or more). When it is finished, the temperature regulator and switches should slide/snap in. If they don't, use a file to make the openings slightly wider. Once you have verified the fit, check your clearance with everything in place, and then screw the faceplate to the filastruder baseboard. Due to the location of the screw holes, you have to mount the faceplate before you insert the switches, etc. & wire them up. Depending on how much clearance you have, you may find it easier to pass the wires through the holes and wire everything up before you mount them to the faceplate.
