Haha (animal enclosure) construction kit.

thingiverse

This is going to seem a bit over-the-top!A "Haha" is a structure used for enclosing farm animals without a visually obtrusive fence. The idea is that you have a gentle downward slope leading to a vertical wall with level ground to the far side. So from one side, it looks like continuous ground - from the other, an uncrossable obstacle.So this is a "haha-construction-kit" that you can put together like model railroad track to make a model Haha!You'd think that modelling all of those individual parts would be a collossal waste of effort - but I have some software I wrote to automate it.So there are two different radii of curves - in 45 degree and 22.5 degree angles. There are straights, half straights and quarter straights. Their surfaces are randomly textured.There are simple connector pieces to hold them together - but honestly, once you're using them in a layout - just glue them down and use filler to blend the edges into your baseboard.
