works in progress... Things for ZMR 250, ideas borrowed from others, but all "drawings" my own thanks to calipers..... The Arm spacers + stock arms brings a total of 12mm clearance between mid and bottom plate, the XT60 holder bit fit perfectly inside this 12mm space, and have a locking bit that holds the XT60 connector very snuggly. The "Lid" was me just goofing around, my daughter likes it... if you go without the top deck, and an naze mini you might actually be able to use it..... hole drilling required... or something sticky.... or... More bits coming..... Added the traditional LED holder, 12mm so it completes the set. I also just added some power distribution boxes, the one with "top" works for both, one is for a banggood 12v/5v bec power distrubtion, you can melt the single pin down to hold the board in... the other one has standard 30mm spaced pins, you can melt them down to hold the board down too....
