I created these for the Muzata LED Channel and diffuser strips so I could use a continuious diffuser cover and have nice smooth bends in the corners to prevent any gaps that would let light shine out. I used a .2mm nozzle with .12mm layer height and while it prints well enough to do the job it's not the smoothest looking print ever but no one is going to be inspecting the back side of it once it's up at the ceiling anyway.

These were the Muzata Channels that I used
