Cookie Cutters - Shapes

DESCRIPTION

Another set of cookie cutters that I've designed over the years.  These are all primitive (or at least non-organic) shapes, mostly used for sandwich cookies.  They're based around a 50mm default width/length, along with a 2x version.  It's all parametric, so I can always include another size if there's demand.

FEATURES

• 1mm wall thickness with chamfered edge, for reasonable strength while still being good at cutting dough
• sturdy top rim and cross supports for rigidity
• Some models have vertical ribs for additional wall rigidity
• Two different sizes
• 15mm depth, which should accommodate pretty much all cookies without using too much filament
• Nearly all internal corner filleted to make cleaning easier

VARIATIONS

Shapes

• Circle
• Heart
• 7-pointed Star
• Linzer Cookie

Sizes

• 1x - 50mm width
• 2x - 100mm width

PRINTING

Material

PLA works just fine, but PETG might resist breakage easier.  ABS could make surface finishing for use with food a lot easier (see below), but I don't have a lot of experience with it myself.

Material Use

4-10 grams, depending on shape and size

Layers/Nozzle

Optimized for 0.2mm layer heights and 04.mm nozzle.  It's possible to print the walls with a single line from a 0.8mm nozzle, but it gets a bit messy.  You want these prints to be as smooth and well-fused as possible for use with food.

Supports

No need for supports or rafts.  You can use a skirt if you have bed adhesion problems, but I haven't needed them

Perimeters and Infill

There is almost no “internal” area in these models.  I'd recommend 2-3 perimeters and 100% infill.  

Other Notes

If you want a specific horizontal size, I'd recommend scaling UP from the smaller model rather than DOWN from the bigger one.  Making the cutting wall much thinner than 1mm can lead to slicing/printing problems, and also gets pretty flimsy.  Scaling vertically should be fine.

POST-PROCESSING

3D Prints and Food

For liability purposes, I cannot recommend that you use 3D prints to prepare or consume food, especially if you plan on washing and re-using them.  3D prints can contain micro-cracks that harbor bacteria, and often warp or deform at the temperatures required to properly clean food utensils.  For that reason, I have not included any pictures of the delicious cookies that I've made with these cutters over the years.

There are several resources on the internet for how to process 3D prints for use with food, usually by coating/finishing them.  I'll leave that as an exercise to the reader.

FEEDBACK

I'm more than happy to consider any recommendations or variation requests.  The designs are largely parametric, so if you have a particular size that you need, or depth of emboss or whatever, I'd be happy to include it here.  I'm also happy to add new shapes on request.  These are just the ones I was inspired to make for myself, but they're pretty easy to make once you have all the parameters set up.
