Model Game Pieces

Using:

Pawn & D6 Dice

Task 1: Model a Pawn and 6-Sided Die Prototype to 3D Print

Task 1a - Make a Pawn

Make a rectangle that is the height and half the width (radius = diameter/2) of the pawn you want to make. A typical pawn:
- Height of 58 mm and a
- Diameter (ie. width) of 30 mm
- Radius = 30 mm /2 = 15 mm.
SketchUp does not like to do small things, like make any curves less than 2.5 mm. For detailed work, use the Scale Tool to scale it up by 10 times. (When finished, you will scale it down.)
- Select the rectangle with the Select Tool
- Choose the Scale Tool.
- Grab one of the green box corners, typing 10, and Enter.
Draw a profile of the pawn on the rectangle so that it makes a face.
- Use any of the drawing tools: Line, 2 Point Arc, Freehand, etc.
- Note: 3D print's weakest areas are between print layers.
- Round out any sharp edges to prevent cracks from forming.
Draw a circle in the blue axis direction of any size with its center of circle on the profile's center edge.
- Tip: delete the face of the circle before going to the next step.
Use the Follow Me tool to take your profile all the way around the circle.
- Tip: preselect the circle with the Select Tool to get the most hassle-free results.
- Make sure it goes around all 360 degrees of the circle without overlapping. If it doesn't or overlaps at all, try preselecting the circle before using the Follow Me Tool.
Make your pawn a Component after you have the shape you are looking for, and delete extra lines.
Check Entity Info to see that it is seen as a solid
- Entity Info will say "Solid group" or "Solid component".
- Use the Solid Inspector to troubleshoot your pawn if it isn't seem as a watertight solid.
This is the time to engrave your initials at the bottom. There are two possible methods:

Engraving with Solid Tools.

Note: Both your pawn and the initials must be seen as a solid by Entity Info for this method to work.

Choose 3D Text Tool to put your initials on the bottom of the pawn.
Use the Scale Tool as needed to get the desired size and engrave.
Select your initials.
Choose the Subtract Solid Tool (3-dot area, 3rd group down)
Select your pawn.

Engraving with Intersect Faces With Model.

Choose 3D Text Tool to put your initials on the bottom surface of the pawn.

Use the Scale Tool as needed to get the desired size.

Edit Component and select the bottom face of your pawn.

Right-click to get the context menu. Choose Intersect Faces With Model.

Delete or Erase the 3D Text. An imprint of the text should be on the bottom of the pawn.

Use the Push-Pull tool to engrave the text into the pawn. Not too deep.

9. Scale the pawn back down to its intended size (ie. 10 times smaller).

- Select with the Scale Tool.
- Grab one of the green box corners.
- Type 0.1 or 1/10, and Enter.

Task 1b. Make a numbered 6 sided die.

Engrave your name or initials for one of the numbers.

Create a 100 mm or 10" cube. (Remember: SketchUp doesn't like small things.)
- Make a 100 mm or 10" line going in the green direction.
- Make a 100 mm or 10" line going in the red direction.
- Make a rectangle that starts and ends at the end of each line to make a 100 mm x 100 mm or 10" x 10" square
- Push/Pull 100 mm or 10" to make a perfect cube.
Place numbers to be engraved on the sides of the cube using 3-D Text.
- Set the Height to 80 mm or 8"
- Check Text filled and Text extrusion.
- Set Text extrusion to 10 mm or 1"
- This is the time to replace one of the numbers with your initials on one of the sides.

Select box the numbers and cube.
Right-click to get the Context Menu, use the Intersect Faces → With Model command.
Delete the 3-D Text numbers.
Use the Push/Pull Tool to push in the letters 1".
Select All and make a Component.
Entity Info should say the D6 is a "Solid Component."

If it is not a Solid, then use the Solid Inspector. "Short Edges" are fine for 3d printing.

Task 2 - Model and Print 5 Game Pieces Total

Make at least three other game pieces to go with your pawn and d6.

Options:

Make 3 different chess pieces.
Make 3 different D and D Dice with engraved or embossed numbers.
Make a combination of different dice and chess pieces.

Specifications

Dice must be fair and useable which means they must be symmetrical. Chess pieces must be easy to identify.
Each object must be in its own component.
Each object must be a watertight solid.
Scale down final pieces so they are no wider than 1 inch (25 mm) and no taller than 3 inches (76 mm).
All pieces will be printed together on a 6"x6" (150 mm x 150 mm) build plate.
Files must be saved with username first.
Must be checked by Mr. Bright. Once checked, an STL file needs be downloaded and exported.
The STL file should be sliced with the Makerbot Print Slicer for the Sketch printers.
