Yogurt cup cutter - parametric

This cup cutter is designed to repeatedly cut 1000-gram yogurt cups.

It creates a bowl with a relatively straight edge.

An M4x16 / M4x20 screw and nut are needed to fix the bell bracket at the desired height.

The 9mm replacement blade of a cutter is secured with an M3 screw.

If anything doesn't fit perfectly, I've included the OpenSCAD script for modification.
____________
Initial long-term tests prompted me to modify the demo model once again.

The new model is more robust, and the screw connection to the base has been changed.

Instructions: Place the cup onto the blade with a slight twist.

Always keep your fingers behind the cutting edge to rotate/pull the cup.

Applying downward pressure should be minimal, as it interferes with cutting and creates a wavy edge.
