Bore Light Pipe

thingiverse

This is a bore light pipe for getting helping shine light into the bore of a gun for inspecting. Print this out using 100% LOOPS of a clear filament. You want the orientation of the print to go along the pipe like a fiber optic. I printed using PETG with 0.6 dia and 0.4 layer heights and also tried 1.2 dia and 0.6 layer heights. Both were about the same performance. Make sure you cut the ends of the pipe to expose the loops of plastic inside.
