qr400 arm spacers

thingiverse

You have a QR400 quadrocopter. The bottom trunk is too narrow to accommodate your rig, but you still want that super nifty folding-arms option? Then take a look at this solution! It's incredibly easy, looks great, and changes the game. You can print these arm spacers in any color you choose - place them on or under your QR400 arms and secure them with longer screws. That's it! When you fold the arms of the QR400, the spacer will follow suit due to its sidewalls. There are two versions included: one for 11mm spacing between the bottom and center plate, and another with a 12mm gap.
