This warehouse has sliding doors. The dock is separate for flexibility.
Be sure to load the sliding doors before gluing on the door track.
The warehouse model has provisions for LED lights and wiring.
I use the connectors from Amazon shown in the photo on all my buildings now to simplify the wiring.
I printed my windows and doors with the glass with a Dual Extruder.
But the files are separate so you can print the frames and apply clear mylar for the glass.
