Turn your unused Picatinny tactical rails from jagged hand-shredders into a comfy, stylish statement. K9ES created three different ladder-type rail covers, BUT ALL OF THEM SHOULD BE PRINTED IN TPU!

Also, think twice about putting this on a real-steel firearm. It may melt.

Excellent for homemade Nerf blasters! I used this in my Caliburn Sniper build on YouTube.

Version 1 has rounded corners, and Version 2 has sharp corners. Both should be printed with supports. Yes, you can print supports with TPU.

Version 3 is more filled in, and doesn't need supports. Looks pretty neat, too.

Enjoy!
