As always, the devil is in the details. Wreckers in general, and crane ones particularly, have to carry lots of tools, equipment, and accessories to cope with whatever situation they encounter. This in turn means lots of storage, alllll the way along the truck, as we see in the blue 1:1 truck above.
This meant printing a LOT of sideboxes and shelves, with hinges:
Color came out weird, but that's silver (ish) diamondplate for the top and a pull door handle, blue body, top and frame, and then dark blue door.
To snap the doors closed, I tried a little socket in the body with an arrow-shaped snap on the door:
That one's a fitment test; the final ones are blue to match the cabinets. They're still a bit tight, oddly, but they do snap.
If you look at the 1:1 up top, at one point there's an access area with flip-down steps to climb up onto the deck. These steps do flip, and have a stop so they only rotate down 90* and then stop. Like the storage box doors they hinge on unprinted (ie 1.75mm) filament, which is melted on one or both ends with a soldering iron to keep it in place. Fiddly, and you can see some boogers there that I hope I cleaned up afterwards. (Man, the camera really doesn't hide my oopses!
While most of the doors open sideways, some open up and the rear most set has both up and down, for reasons we'll see in a minute.
The rearmost cabinet bottom shelf houses the controls, a set each side. This would prolly have been better fabricated if I had any fabrication skills, but at this scale I don't. The Bambu printer at least did well with many colors and so I can color code here just like the TX.
That thing is like 1/2" tall, maybe 3/4" deep, and a few inches wide, so it's TINY. And took seven hours to print (but if you know how the Bambu switches colors you know why.) No matter, it's the best I could do and it's a fun detail.
Long shot showing all the boxes.
