Dog Treat Cookie Cutter

Thanks to this cool design from FabThis on Thingiverse we were able to make a few dog treat cookie templates for our friends at Naked Dog Bakery (also here). 

We tried making some different sized templates but really the design challenge was to create a stamp that can be used to make many at a time.

Tinkercad has its limits, but it was a good enough program to multiply and merge 8 of these templates together.

One great template times 8!

The first print suffered from low quality so we made some revisions to the infill, wall thickness, temperature, and speed and managed to produce a decent 8-up template.

Personalized 3D Printed Cookie Cutters

I saw this great item from CopyPastry for sale on Etsy and thought — hey, why not see if I can make something similar?

So, following the good advice of a few online how-to’s (e.g., convert photo to line drawing) I found my way through to a printable model that resulted in a unique birthday gift for a good friend.

Here’s how:

Step 1: Select a high-resolution photo of your subject’s face. I used one in jpg format.

Step 2: Desaturate the image and then use the Difference of Gaussian filter to find the edges and create the line drawing. Save as a jpg.

Step 3: Import the line drawing into Inkscape and use the Trace Bitmap to create an svg file.

Step 4: Import the svg file into Tinkercad and create the 3D

file. Then export as an stl file.

Step 5: Import the stl file into Cura and configure the print settings.

Step 6: 3D print the file.

Step 7: Make cookie dough (I used the Sugar Cookie recipe on p.612 of the Fannie Farmer Cookbook), heat the oven, and stamp out the cookies.

Step 8: Eat and be happy.

You, too, can make your own likeness in cookie form. Yum!

A few things I learned:

  • Creating contiguous lines in the line drawing makes it easier to print a template that will easily cut out a shape; too many points make it a bit more difficult to print the template.
  • Check to make sure you have some distance between the walls of the shape and the details of the face. You may have to experiment and print a few different models.
  • Fine points make it harder to remove the dough from the template once you’ve cut it out.
  • It’s hard to wash 3D printed templates; the layers make it difficult to prevent build-up in the crevasses.
