I don't need these cool items at the moment, but fantastic job guys!
Jason, I have mucho experience with injection molded plastic part design (batteries and medical devices) if you want to chat about how to handle the thin walls of the rail covers. There are tricks and cheats...

Tom- not sure if you're referring to RAIL CAPS/COVERS or FLAPS.
Jason has mentioned he'll try to replicate the rail caps in the future, but hasn't yet. Think towers are next up for him.
