80/20 enclosre build

hey guys looking to build an enclosure, but stumped with proper framing and hinges.
so far I have an x carve with screw drive so the front stick out a little farther
my dimensions are
H = 20" (linear z)
W= 42.5"
L= 43.5"

just wondering where do I start and parts i’d need. Also how much clearance should I give with these lengths. like 5".
any help would be greatly appreciated
