|Step_Content=<translate><!--T:5-->
Open the website [http://www.makercase.com www.makercase.com]

<!--T:6-->
No registration or action is needed.

<!--T:7-->
Design with Makercase:
* Set the units to millimeters

<!--T:8-->
* Set the dimension as EXTERNAL and set the size as 40 width, 40 height, 40 depth

<!--T:9-->
* Set the material thickness: we suggest using 4mm using  the “Custom material thickness” option

<!--T:10-->
* Select the Finger mode for the Edge Joints option

<!--T:11-->
* Set the tab width to 4 mm</translate>

We are going to create a dice just using Makercase
* Double click on the faces to add text
* Write the number from 1 to 6 one on each face
[Tip: To create a correct regular dice the sum of opposite faces should be 7: 1 opposite to 6, 5 opposite to 2, 4 opposite of 3]</translate>

Vector cutting: you can set the thickness and the color for the cutting lines (we use thickness 0,01 mm and color blue #0000FF)

<!--T:16-->
[Tip: we suggest you to set the line thickness at the end, because very thin lines can be difficult to visualize]

<!--T:17-->
Text engraving: set the color to the desired color for raster engraving. We use #808080

<!--T:18-->
Check “Convert Text to Vector Paths”

<!--T:19-->
Laser cutting kerf: 0.1

=== The Laser cutting kerf === <!--T:20-->
This is the most important setting and is the also one of the concept this activity aims to explain.

<!--T:21-->
“Kerf” is the material that the laser burns away while cutting. It depends from laser source wattage, the lenses used for the laser, the kind of material and its thickness.

<!--T:22-->
We suggest to set 0,1 mm. From our tests in fact we noticed that a general value, common to most lasers and various material, is 0,2 mm.

<!--T:23-->
We suggest to use “soft” materials, as poplar plywood. Acrylic/plexiglas will be difficult to join, and MDF or hard woods can require some pressure on the slots to be joined.

<!--T:24-->
If you wish to expand the concept of laser cutting kerf, tolerances, going from 2D to 3D, you can experiment using different slight different settings to create boxes: 0,9, 1, 1,2 mm… the students can have an experience on how a small change in value can create different effects when working with interlocking parts.

|Step_Title=<translate><!--T:25--> Understanding the importance of sizes</translate>
|Step_Content=<translate><!--T:26-->
Aim of this step is to create a box that contains the dice, with a perfect fit that won’t let the dice move but that is not to tight because the dice needs to be removed easily.

<!--T:27-->
Students must think about the size and dimensions of the dice just created. Since the side measures 4 cm, we cannot create a container that has an internal size of 4 cm, as the dice will be constrained into it. We need to create a container that is slightly larger.
* Set the dimension as INTERNAL and set the size as 42 width, 42 height, 42 depth

<!--T:28-->
* Set the material thickness: we suggest using 4mm using  the “Custom material thickness” option

<!--T:29-->
* Select the Finger mode for the Edge Joints option

<!--T:30-->
* Set the tab width to 8 mm
Changing the tab width  changes the results of the box. A higher number of narrow tabs makes the box really difficult to open, while wider tabs make it easy to open if needed.
* Click on Generate Laser cutter Case Plans and follow the same settings of the previous step.
* Set the kerf to 0,08 mm. This will make the box easy to open to access the dice

Tutor can ask the students their feedback on the ability to interlock 2-dimensional parts with different ease.

<!--T:35-->
Students can design further cases that can be used as simple boxes, special containers, pen holders and so on.</translate>
