2020 Diffuser insert for led strip

This is a simple led diffuser that inserts neatly inside the rail of 2020 extrusion.  

You can slip  this into the rail overtop a LED strip, providing a nice diffuse glow. 

Created simply using shapes in Prusaslicer.  The inside of the rail is 10.5mm, so I made these 10mm wide, and 0.2 mm thick (single layer). 

Printed in white PETG, more flexible that PLA so you can slip it in one side, then press down with a pen cap or something blunt to get the other side in.
