### Day 185 - Wishbone

Easy mashup time: Today we printed SimplusDesign's Wishbone Cookie Cutter Set on Thingiverse and Eckerput's Rolling Pin Spacer on Thingiverse so we can make some cookies! Also, a bonus: The rolling pin spacer can be resized into a really simple bracelet to use as a reward for winning the wishbone-breaking competitions that will ensue.

Thingiverse link for rolling pin spacer: http://www.thingiverse.com/make:68122

Settings: MakerWare .3mm/low on a Replicator 2, with no raft and no support.

Technical notes: Eckerput made his rolling pin spacer in OpenSCAD, which makes it easily customizable to different rolling pin sizes and dough thicknesses. It's a great example of simple OpenSCAD code; if you're a beginner you could start with this example and then work on extending and modifying it into other projects:

// Rolling Pin Spacers
// all measurements are in mm

// by Eckerput
// http://www.thingiverse.com/thing:38943

// Diameter of rolling pin in mm (best if slightly smaller than actual)
pin = 46;
pinr=pin/2;

// How thick you want the dough to be in mm
Dough = 5;

difference () {
cylinder (h=7,r=pinr+Dough, \$fn = 200);
translate ([0,0,-2]) cylinder (h=14,r=pinr, \$fn = 200);
translate ([0,0,-2]) cube([pinr+Dough+2,2,14]);
}
