Picatinny Rail Filler
thingiverse
Tired of seeing picatinny rails on Star Wars blasters, I made a quick design to fill them in. Glue these in place and then you can fill and sand over them to create a smooth surface. This was designed to fit a CYMA M4 but probably will fit others, you may need to re-scale for your own rail. Print at least 5 of them at a time to allow for enough cooling between layers, I recommend 10 or more. Printed out of PLA at 210c. Make sure the bed is cool before removing them or you will warp the bottom and they won't fit properly.
