Hinged Smart Citizen Kit Case with Air Vents

SummaryI need YOUR help! I originally designed this for somebody else and we didn't get to finalize the design. I don't have a Smart Citizen kit but there are some things on this case I would like to get do away with. For example, currently there is spacer plate between the battery and the unit, I don't think is necessary(is it?). Also, I've considered doing away with the TPE grip mat that goes on the bottom and putting on mount holes. I need feedback from people who have on of these on dimensions that need to be changed etc. Any feedback is appreciated. For the hinges you'll need some M3 bolts and nuts. Happy printing!
