OpenSCAD Czech Hedgehog

I liked the design of don_eldarro's "Czech Hedgehog" in that it could be taken apart when not in use, but I wanted something that looked a bit more like the real thing. Getting something that looks exactly accurate with this three piece approach isn't really possible, but I think this gets a bit closer to the source object.

There are still a few adjustments I am thinking of making, but this is close enough to being finished that it should be safe to print.

I implemented this design in OpenSCAD, so take a look at the script if you want to make some tweaks. Of particular note is probably the variable used for tolerances; on my printer .5 mm is the sweet spot, but if you've got better hardware you could probably tighten that up a bit.
