DIY cookie

    Perhaps you read the “Renewal” post about acquaintance of children with the profession of a programmer - As we explained to children who such a programmer is (I recall that “Renewal” makes interesting free events for children with the best Russian and foreign specialists. And they broadcast freely throughout the country).

    The next lecture (February 22) was about confectioners . An idea came up - is it possible to make a “link” between programmers (IT specialties) and confectionery? I talked with the organizers - it turned out that there were enough intersections: there are 3D printers that print sugar, you can 3D simulate molds for filling with chocolate, there are Delta 3D printers to create baking, there are chocolate 3D printers.

    But we stopped at the simplest - this is the creation of 3D cookie cutters.

    It was necessary:
    • create a 3D model of the form,
    • print on a 3D printer,
    • make cookies
    • treat the guys at the event

    There were only a few days left before the event, about how everything was - from the idea to the embodiment, there will be a story.

    Find / come up with a cookie shape

    Molds for cookies is not something new, remember about them was a post Habré, and we hakspeyse printed mold, and the participants were baked , and there you are:

    But I wanted to make cookies themed - by February 23 (the event about confectioners was February 22). Immediately I thought to make a star, but somehow it’s not original, so I decided to make a mold for the plane.

    After a short search, I settled on this - get acquainted with the “T-50”, a 5th generation fighter:

    Here is its model:

    Based on this model, using the free and open GIMP graphics editor , a mask was made: The

    mask for the form is ready, now you need to do 3d model.

    Make a 3D model of cookie cutters

    The question of where to do it was solved simply - service . This is a free specialized service for creating cookie cutters:

    The principle of the service is simple - we click on the work area with the mouse and lines are created between the points where we clicked, after the figure is completed (clicking on the starting point), the figure is displayed in the upper right - preview.

    For example, let's make a simple figure, a triangle:

    We see on the right a display of the shape created by the program (in addition to the outline, the program creates a small frame at the initial level - this increases the strength of the model). It is also possible to edit the “nodes” of the model, and we can click on the “edges” and make convex / convex contours.

    Below the preview screen there are settings for the size of the created 3D model:

    - maximum shape size (Large 4 ") - (4 inches = 10 cm)
    - height (0.65") about 1.5 cm
    - wall thickness - 2 mm

    You can change these settings for receiving molds of different sizes.

    And below is the button to download the cookie form - Download 3D File . We click, and we get a cooke.stl file (3D model in STL format).

    The service has the ability to download pictures - Trace . In this case, you can "circle" the outline of the picture.

    Download our template. And we can “click” along the contour.

    But to automate the contour, the service provides the function "Magic trace"- This function allows you to find the contour of an object. We click on it, and after that - we click on the "body" of our airplane circuit, and the system itself creates a circuit. Here's what happened:

    3D models were made - for different sizes of cookies. STL files can be downloaded from here .

    Here's what the created STL models look like in Cura 3D printing software:

    You can read more about estimating printing time in Cura software here (having a 3D printer is not necessary).

    Print 3D model on 3D printer

    The guys from the Moscow hackspace Neuron ( 3D Printing Laboratory , thanks to Ivan) agreed to help with the press .

    Here's what it looked like:

    Printing process:

    And the finished mold:

    Make cookies

    In the manufacture of cookies helped Julia (project manager Renewal).

    Here are her photographs of the manufacturing process, based on the recipe :

    The dough is made, rolled out, and on it we use the cookie cutters to make cookies:

    And then bake in the oven:


    Here is the story about 3D cookies at the event:

    And Julia shows the result:

    A fragment of the broadcast about 3D cookies.


    If you want to make a form using the cookiecaster service , then you have a bonus.

    I talked with Ivan (Moscow) from the 3D printing laboratory , and they provide a 15% discount all March for printing 3D cookie cutters (the average price is 150 rubles / form).

    Also we, in Yekaterinburg in the MakeItLab hackspace , provide the entire March with a 15% discount for printing cookie cutters.

    Can someone make cookies by March 8th :)

    You can find many ideas for 3D models on the Thingiverse service, for example, the request " cookie cutter " - returns more than 1000 options.

    Let me remind you that you can search for 3D printing in your cities - in hackspace, in fablabs, in CMIT, and just in companies that provide 3D printing services. Printing cookie cutters is recommended from PLA plastic.
