This is a palette-shaped tool for measuring how much spaghetti makes a serving (or two or three or four). It might work for other small pastas, but I'm not sure.
(There were some other things posted that did this, but I had trouble getting Slic3r to handle any of them.)
Serving size measurements are from the plans here: http://www.freepastatoolsplans.com/Assembly_4.htm
- Fill appropriate hole with spaghetti.
- Boil water.
- Cook spaghetti.
- Add sauce, cheese and other ingredients as desired.
For this design, I drew it in Illustrator, exported it as a DXF with Inkscape, extruded it in OpenSCAD and printed it on a Printrbot using Pronterface and Slic3r. All source files are attached.
