Double Decker Bus & Chassis (Parametric)

Update 12/4: Added STLs for smaller, thicker bus. (See below.)
Update 12/4-b: Updated OpenSCAD -- fixed some bugs, added some parameters. (10 d/l)

A friend of mine posted a cute metal double-decker bus toy, and I thought it would make a great 3D-printed toy. Using the photo as a rough guide, I modeled this bus in OpenSCAD. It's parametric so you can change things like the overall dimensions, thickness, wheel sizes & offsets, axle sizes, rounding, window height, stile width, trim height, and more.

The original toy said "Welcome to Hyde Park," so I added an *.SVG for that as well. (The font is Garamond, but it's converted to curves in case you don't have that font.)

I could only see one side of the toy from the photo, so I just guessed at the rest. It's not identical to the toy, either -- I took a couple of shortcuts. But it's immediately recognizable as a double-decker bus by both my kids, so I'm pretty satisfied. :)

STL files include the full plate, the bus shell, the
