Parametric round cookie cutter generator

A parametric generator for a round cookie cutter with rounded and smoothed edges and corners.
We Aussies call them bikkies (short for biscuits) which is what you'll see in the filenames. The closest we have to US biscuits are scones, but they're sort of more cake-like. Great with jam and cream.
Nothing stopping these getting used for cookies, biscuits or scones. I made a set to cut donuts from my Nanna's donut dough recipe - the models are included here. I've also included a set to cut pie crusts for single serve pie makers (we also love a pie and sauce).

There are two versions here:
1. The main version creates the wall using a sliced up sphere to give a smooth taper to the outer edge without tapering too slowly to the cutting edge, and it uses minkowski() for smoothing the corners around the rim. This gives a much better look and smoother print results, but takes a toll on the rendering engine and can be slow in the online generator.
2. The simplified version uses simple cylinders
