Summary

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 bready cake-like. Great with jam and cream. Nothing stopping these getting used for cookies, biscuits or scones though. 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. A test run looks like it's running fine though.
2. The simplified version uses simple cylinders and angles, and will give a much faster render if using the online generator. Same dimensional mechanics and functionality, but it just doesn't look as nice.

If the generator spits the dummy you can download OpenSCAD here: [https://openscad.org/downloads.html#snapshots](https://openscad.org/downloads.html#snapshots)
 

Changeable parameters include:
Inner diameter
Wall Height
Wall thickness
Rim width
Cutting edge width

Defaults give best results for 0.4mm nozzle. I suggest a 0.2mm nozzle if you want to reduce the cutting edge any further, but the default does a good job at printing and cutting anyway.
