Snowman Bobblehead

I really wanted to make a bobble head but I found it next to impossible to take one of the published STL files and add in a plastic spring for a bobble head.
So I put a lot of work into this and had to write some custom python code to make it happen.

In the end I managed to merge STL files and Openscad by converting the STL to an Openscad polyhedron.
thingiverse will not let me upload .exe or .py files so I can't post them sorry.

I probably could have cleaned up the print a bit, but I was pretty happy with the result.

It bobbles nicely.
I printed it in two pieces because the spring needs to be held in place while it is printing, so I had to provide access to the spring so that you could remove the supports. I used needlenose pliers to remove them.

So print both pieces, don't make it too much smaller as the spring is designed for 0.2mm layer height, it might get too weak if you scale it down very much.
