This is the 4th in the D&D dice, however, it is not truely a Platonic Solid.
I put it in so you can make a whole set of dice.
Like in most of the previous Platonic Solid/Dice Instructables we will start with a triangle.
Step 1: Materials
A new addition to our materials this time, a 30/60 drafting triangle.
30/60 Drafting Triangle
Nail Polish Remover: Just incase you accidentally glue your fingers.
Step 2: Making Our Base Triangle (Step One)
1. Turn the paper in a Landscape position.
2. Measure and mark 6 cm and 3 cm from the left side on the top and bottom of the paper.
3.Connect the marks at top and bottom lightly.
4.Using the ruler measure 6 cm from the left hand corner on an angle until it touches the 3 cm mark.
5.Repeat the process from the other side. The marks should come to a point and make a perfect 6 cm isosceles triangle
6.Double check the measurements and make sure all 3 sides are exactly 6 cm.
7.Carefully cut the triangle out.
Step 3: Making the Base Side Shape
7. Place the triangle template against the previous cut mark to make an inverted triangle on the paper.
8. Use the template to draw another triangle directly on top of the one you just drew.
9. Cut out the diamond shape.
10. Lightly draw a line between the two horizontal points .
11. Lightly draw a line between the two vertical points.
12. Place the 30 Drafting Triangle along the midpoint lines and lightly draw in the 30 degree line up to the midpoint on both sides.
13. Cut the bottom portion just drawn off. You now have the Base Side Shape.
Step 4: Making the Top and Bottom Half of the D10
13. Using the template draw the base shape.
14. Draw another base shape using the long side of the previous shape as one long side on the the new shape.
15. Repeat the last step a total of 5 times. This should net you a hexagon divided into 6 equal pieces.
16. Cut the Hexagon out.
17. Cut one of the Base Shapes out of the Hexagon.
18. Make another Hexagon minus the Base Shape following the above steps.
Step 5: Joining the Top and Bottom of the D10.
19. Score the lines on each triangle.
20. Hold a ruler over the scored lines and gently lift the corner, this will allow a nice crisp bend in the paper.
21. Join the gap in one of the pentagons, using a tab and superglue.
22. Join each of the sides on the top to a side on the bottom.
23. Finish the D10 by closing the gap in the top penatagon.
Step 6: Paint
18. Paint, I used red for mine.
Now we have a D4,D6,D8 and D10.
The D20 is next.
