Domino-Style Blocks

This is an introductory project so you can get acquainted with the basics of 3D design. To create domino-style blocks using 123D Design, you will select a box and describe the dimensions of a domino-shaped block.

Go to Primitives and drop down to Box.

Left-click and release. A cube will appear. Move the cursor to the lower left area of the screen.

Type 8, then press the Tab key. Type 50, then press the Tab key. Type 25. Press Enter. This will create a box that is 8 mm by 50 mm by 25 mm.

Move the cursor to 123D in the upper left corner. On the drop-down menu, find Export STL and you are ready to print your first project.

Name the file "Block" and the ".stl" will be attached. Now you can send "Block.stl" to your 3D printer and a domino block will be created. This is called a "print" file and it is written in a language 3D printers can understand.

To save your design file (in case you want to add other details later), move the cursor to 123D and drop down to Save.

Print the block.

MAKING DOMINO-STYLE BLOCKS USING SKETCHUP

This introductory project can also be created using SketchUp. Start with a new file. Go to Camera, then drop down to Standard Views, then Front. Left-click and release.

Choose the Shape icon. Left-click and release. Drop down toRectangle. Left-click and release.

Move the pointer to the intersection of red and blue lines. Left-click and hold. Move the cursor right and slightly up. Type 50, 25 and press Enter. Release the left-click.

Choose the Zoom icon. Left-click and release. Move the pointer to the rectangle. Scroll until the rectangle fills most of the work area.

Move the cursor to the Push/Pull icon. Left-click and release.

Move the cursor inside the rectangle, close to the bottom. Left-click and hold. Move the cursor up slightly. Type 8. Press Enter, then release the left-click.

Go to the Select icon (first on left), left-click and release. Go to Edit, then drop down to Select All. Left-click and release.

Go to the menu at the top and choose File, then drop down to Export STL. Left-click. This file can be used to print a domino block.

To save the design file, choose File, then Save.

Spinning Button

To create a spinning button, you will draw a circle, make that circle thick, then cut two holes in the thick circle.

Start by moving the cursor to the Sketch icon.

In the drop-down menu, move the cursor to Circle.

Left-click, and move the cursor down onto the grid.

Left-click two times. The first click will result in a check mark. The second click will produce a small dot.

Move the cursor. A box will appear with the message "Click to specify diameter."

Type 50 and "50" will appear in the box.

Left-click. Move the cursor to the Construct icon at the top of the page.

Drop down to the Extrude option. It is the far-left icon on the dropdown menu.

Left-click on the Extrude option and the check mark will go away.

Move the cursor inside the circle.

Left-click inside the circle. A box with "0.00 mm" will appear. Type 3 and "3" will appear in the box. Left-click.

Move the cursor to the upper right corner of the screen. Place the cursor on top of the cube. This cube indicates the view direction.

Left-click and you will now view the button from the top.

Move the cursor to the Sketch icon at the top of the screen.

Drop the cursor down to the Circle icon.

Left-click. Move the cursor down into the circle. There is a tiny dot in the center of the circle. Move the cursor right from the center to the first intersection of grid lines.

Left-click two times, then move the cursor. A box with a number will appear.

Type 3 and it will appear in the box. This is the size of one of the holes in your button.

Left-click. Move the cursor to the Construct icon at the top of the page.

Drop down to the Extrude icon.

Left-click.

Move the cursor inside the small circle and left-click.

Type –3 and left-click. The "-" sign makes a hole "into" the button. If you had typed -2 and clicked, it would have produced an indentation, not a hole through the button. If you had typed 3 and clicked, a small cylinder would have protruded outward from the button.

Move the cursor to the Sketch icon at the top.

Drop the cursor down to the Circle icon.

Left-click. Move the cursor into the large circle, left of the center dot at the first intersection of crossing grid lines.

Left-click two times, then move the cursor slightly.

Type 3 and note that "3" appears in the box. Left-click.

Move the cursor to the Construct icon.

Drop the cursor down to the Extrude icon.

Left-click, then move the cursor into the large circle.

Move the cursor into the small left circle and left-click. Type –3 and "-3" will appear in the box.

Left-click.

Move the cursor toward the cube in the upper right corner. As the cursor approaches the cube, a small house will appear on the upper left corner of the cube. Left-click on the little house.

Move the cursor to the upper left, over the 123D in the corner.

Move the cursor down to Export STL and save your file for printing.

To save the design file, move the cursor to 123D in the upper left corner and drop down to Save.

Obtain a piece of string about 1 meter (3 feet) long. Thread the string through the button.

Tie the ends of the string together. Now, holding the ends of the string, spin the button about 20 revolutions. Gently pull and relax the ends of the string, and the button will continue to spin.

MAKING A BUTTON USING SKETCHUP

To create your button, go to the fifth icon from the left at the top of the screen (Shape). Left-click and release. Drop down to Circle. Left-click, release, and drag the circle to the intersection of red, green, and blue lines. Left-click and hold. Move the cursor slightly. Notice the box in the lower right that says "Radius" and displays a number. Type 25 and depress the Return key. Release the left-click. Move the cursor to the magnifying glassat the top of the screen (sixth from right). Left-click and release. Place the magnifying glass over the circle. Scroll until the circle gets larger.

Move the cursor to the top of the screen, sixth from the left (Push/Pull), then left-click and release. Move the cursor inside the circle (circle will fill with tiny black dots). Left-click and hold while moving the mouse downward. When the box in the lower right ("Distance") is "3.0mm," release the...
