FIGURE 13.13
Screen grab from SketchUp showing the process of extruding the walls.
2. When you have outlined all of the walls and made them a solid color, then make the loor a white
material. Note: You may want to change the outline color in Window/Styles/Edit to a red or green
so it is easier to see while you are outlining the black-and-white maze pattern.
3. Extruding the walls. When you have inished all the walls, extrude them to the height of 25 milli-
meters as shown in Figure 13.13. Now, you should see the maze starting to form. The walls will
extrude with the color you used to ill the top surface.

You may want to hang up the printed object. If that is so, add a punched tab to the front side of the maze base
as shown in Figure 13.14. Just draw in some cut lines on the face of the base, extrude a square tab from the
front face of the box. Make a tab 10 millimeters thick and about 30 millimeters deep on the front face. Trim
and add a hole for hanging the maze from a string or chain, something with a radius of 8-10 millimeters
should be suficiently large. In the prototype, printed at 100 millimeters to the side, this 10-millimeter tab
should be just over three-eighths of an inch thick.
Note: In the virtual world, you can sink some of this model into the ground if the base looks too thick.

If you like the look of this maze and want to test it out in the virtual world, then save it as “my_prototype_
maze.skp” and export it in the COLLADA (.dae) ile format from SketchUp. This is under File/Export/3D
model in the top menu. Take the default options when you export. You are going to export this model twice;
make two iles for uploading—the mesh model ile called “my_prototype_maze.dae” and a physics ile for it.
