Bolt on Tail Tidy for DR 650.
Not tested in the elements for strength, but I printed in PETG. Will be testing when warmer weather comes around.
After printing flat at 100% infill, use heat gun to soften and fold at 45 degree angle from the square side.
You can experiment with making it thicker in your slicer.
Template came from https://drriders.com/diy-license-plate-adapter-t8213.html and I made it into an .STL
