You have a set of number cookie cutters at home, you may even have the normal operations + - x /. What is you have an irrational urge to transcend the ordinary and let your imagination take you to the golden cookie!
This is the set for you. It includes some of the most opoular numbers not included in the standard 0-9 set as well as a few of the less common variables and the integral opperator.
The set contains:
e, i, pi, phi, Sigma (big and little), i, sqrt(-1), integral sign.
If you feel I have missed something out I may do requests if you ask nicely and promise to post pictures.
To get all the cutters in one handy lump, download the zip file. It is way down near the bottom of the list and I can't re-order them.
To make a geeky maths cutter, first download your choice of symbol (or download the zip file to get all of them in one handy package) Print it then make cookies.
This site has a great recipe: thehungryhousewife.com/2009/10/sugar-cookie-and-icing-tips.html . Roll thin, cut out, bake and eat. Don't forget to make bad jokes about imaginary cookies!
If you want to create your own cookie cutter you will need:
An image editor that can export to DXF (I use inkscape)
The cookie cutters are generated by the CookieCutter2.scad OpenSCAD script. They use different layers of a DXF to make different parts of the cutter
This becomes the blade of the cutter
This is where you draw things to hold floating sections of the blade (the hole in the 0)
This defines areas to remove the flange from (the hole in the 0)
Not used for this set, see Thing 32431
Have a look at the two SVG files included here for examples of how the layers work.
Create your image and massage all layers into a workable form and save as a DXF (look at repraprip.blogspot.co.nz/2011/05/inkscape-to-openscad-dxf-tutorial.html for instructions)
You will need to edit the CookieCutter2.scad file to open your dxf. Run the script to generate the cutter, it may take 10 minutes or so depending on your machine. Export the STL and start printingyour own cutters. Don't forget to post them here!
