ProtoCycler+ V1 Hopper Dust Cover

Dust cover for the intake hopper of the “ProtoCycler+ V1” filament extruder. It uses M3 bolts and a flat of PET from a cut from a soda bottle as a see through window. Includes a little handle that bolts onto the top for easy use. 

To make the window from a PET bottle, cut a smooth sided soda bottle along the lines as shown in the picture of the soda bottle. Then hole the new plastic sheet you just made up to the printed top/cover and trace the edges of the pocket the window needs to fit in. Then cut along the traced lines and you now have a PET window panel. Next place the panel inside the lid and mark each hole location that you will need to drill or punch out.
