I'm cheating a bit to get the banking, and the process I use limits how high I can go. The track, grid, borders and the sort-of-grassy texture is a 2D image used as a height-map. So to get the banking, I simply lighten part of the image to "raise" the track. It works well, but the greyscale range of a PNG is only 0-255, so you can get accuracy OR range, but not both... but a 1/4" or 1/2" (as shown) raise works fine for a 2" wide track, I think. For a 4" wide track, getting enough height starts limiting the accuracy of the height-map.

A *very* unfortunate side-effect of that process is that OpenSCAD ends up eating memory like crazy. Creating the STL for that part requires 20+ gigabytes of memory...

Silly me, and here I thought of a real-life track for some reason.

I haven't got Arenas. Back in the day, we used to draw & print tracks for our games rather than play on pre-defined. So we could make the tracks suit out style of play. Also, the Octagon was and still is awesome :-)

3D printing is great for people like me - with no real-life modelling skills :-( Can't paint very well, either. I'll try and publish the pieces (& the code to semi-automate the creation) when the whole process is a bit less hackish than it is now.
