So I'm working on printing my last (hopefully) revision of the battery base plate for the Micro Alien. I'm also attempting a video lapse of the print. I purchased some 'space gray' filament for this purpose. This base plate is meant to add a bit of thickness to the bottom of the frame to keep the screw heads from possibly damaging the battery pack. I don't know but I think that is all it will be good for. I'd like to think it will add some rigidity but the screw heads will only be seated on 1mm thick PLA material. So there is the possibility of the plate breaking in a crash. This is what is called R&D. if that doesn't work, then I'll add a half mm to the thickness and make another one.
