The diorama is based on underpass and/or tunnel designs with a top area to be use as car park or placement for garage diorama that I made previously.
Checkout my showcase video:
I have also included 2 variants that is just a car park on top:
With fence (Only the top is shown in this screenshot):
No fence:
The diorama is separated into multiple parts for easy printing. All files are separated into folders for easy printing. The files are arranged as follow:

Optional parts screenshot:
Additional Parts Used In My Build
LED strips (for lighting the garage and the underpass/tunnel area)
HO scale light pole (as additional lighting outside the garage and car park)
Step Up Power Controller to convert 5V USB power to 12V to run LED strip
400 ohm resistor to reduce voltage to run 3V HO scale light pole
M2.5 bolt & nuts (at least 8x set)
Plenty of double sided tape (For taping base to flat base)
Good glue for holding the main pillars in place (Highly recommend to use glue since the upper area is held up by just the T-pillars and its cross beams)
Print Settings
Nozzle size = 0.5 mm (0.4 will be printable and smaller better) Layer height = 0.2 mm
Filament change layer for colours on "FlatBase - 2 Lane Road (Actual Size).STL": 1) Start (Road lines colour, mine is in white) 2) Layer 5 (Overall road colour, mine is in black)
Filament change layer for colours on "UpperFlatBase2 - Plain - Small Sidewalk.STL" & “UpperFlatBase2 - Plain.STL”: 1) Start (Overall road colour, mine is in black) 2) Layer 8 (Sidewalk colour, mine is in grey)
Assembly (Based on my photos build)
The car is just placed on the diorama, there are no holes to tie the cars down by wire.
Check out my assembly video to give you a better idea on how the build suppose to go:
