3. Computer controlled cutting

This week I learned how to use Vinyl Cutter Device, how to use the Laser Cutter, and designed and cut a parametric press-fit construction kit.

Vinyl Cutter

Steps in the Cricut Design Space

  • I downloaded and installed the software Cricut Design Space from the website: Cricut

  • I created a new project and uploaded the clipart I’ve chosen. Then, I’ve removed the white portions of the background, and selected upload type as “cut image”.

  • I’ve selected the clipart and clicked “add to canvas”. I modified the size and position of the clipart, and selected “make it”.

  • I clicked continue and connected the laptop to the Vinyl cutter device via USB cable.

Steps in the Vinyl Cutter device

  • I fixed the Vinyl paper in the light grip, and put the light grip in the device, and make sure the device is set to cut vinyl.

  • I’ve clicked the arrows button for the light grip to be pulled. Then, clicked “C” button and the cutting process started:

  • The final results after removing the not needed portions and sticking it on a paper:

Press fit construction kit:

For this task, I worked with my friend Kumail, to make a Classic football using pentagons and hexagons, connected by joints.


I got help from this helpful tutorial about constraints:


  • I draw a regular hexagon using sketch, create then polygon, and draw a construction line from the origin to the midpoint of one side:

  • I made a joint in one side of the hexagon, made it perpendicular, and symmetric to the construction line

  • I removed the side, and connected the other sides to the boundaries of the joint. Then I removed all the other sides, and made the two lines constituting the remaining side to be parallel:

  • Using the circular pattern tool, I duplicated the side in a symmetric way with respect to the origin point, and connected all sides using the ‘coincident’ constraint:

  • Now changing the joint width and length, or the side length, could be done without altering the shape:

  • to fix the entire shape, I draw a vertical construction line, and use the ‘fix’ constraint on it, so the whole shape became black:

  • I added parameters and assigned the joint width and length, and the side length to them

  • I made extrude to the shape and made a sketch on top of it, then exported the sketch as .DXF file:


I made the joint in a similar way to the hexagon

  • Using mirror tool about a line:


It was done by Kumail, and the processes is similar to the hexagon design.

Printing and Assembling

And now, this is the final shape we got!!
