Mistral coffee scale/mister: hopper extender

The crowdfunded version of the Mistral coffee bean weigh-scale + mister had one major defect - the input hopper was too small for most uses. This insert fits into the hopper and allows you to use up to about 25g of beans, without interfering with the ability to pour them out.

This is the nth (and hopefully final) iteration of this design, created in openscad so you can tweak it for minor variations in manufacture that may have occurred at this early stage. Hint: You want a snug fit so it doesn't fall off when you pour the measured beans into your grinder. Of course if it doesn't fit snugly you can use a bit of glue to hold it in. Or adjust the three perimiter sizes and print it again.

This version is 5mm higher to allow more room, and has a bevel on the bottom so beans are less likely to get caught and remain in the hopper when you pour them into the grinder.

I recommend printing with a food-safe PLA or PETG even though it will only have brief dry contact with your beans. And, of course, print upside down to avoid support or messy overhangs.

This work is dedicated to the Public Domain, since (a) I believe that any and all works primarily created by an AI should be public domain, because most AI training material is either stolen (see e.g., the Anthropic class action suit), or taken from publicly-available information (b) Mistral's market share for this early model was to tiny that nobody would make a killing, or even a profit, selling this thing anyway. :-).
