Introduction: Twisted Pentagonal Prism Pencil Holder
This is a guide on how to make one
Step 1: Glue a Blank A4 Paper Onto High Impact Polystyrene
Put the paper onto the corner as shown
Step 2: Set a Protractor As Shown and Make a Mark at 70º
Step 3: Draw a 15cm Long Vertical Line
Make sure it lines up with the Mark your protractor made
Step 4: Make Another Line As Shown
Make the line on top of your angled sides. Be sure that this line is straight and going all the way across the paper, as it will make it easier to make angled rectangles.
Step 5: Make a 5cm Measurement As Shown
Start at the top of your vertical line
Step 6: Make Another Mark Angled at 70 Degrees, Starting From the 5cm Mark You Made
This will help make your angled rectangle
Step 7: Make Another Line From the Mark As Shown
This will complete 1 angled rectangle
Step 8: Make 4 More Angled Rectangles With the Same Measurements
Step 9: Cut Out All of Your Angled Rectangles
Step 10: Make a Diagonal Line As Shown on All of the Recrangles
Make sure all the lines are going the same direction
Step 11: Cut Across the Diagonal Line
Step 12: Making a Pentagon. Make a 5cm Line
Make sure the sides of the pentagon are the same width as the angled rectangles. Each angle should be 108 degrees to make the perfect pentagon
Step 13: Line Up a Protractor at 108º and Make Another Line
Set up as shown.
Step 14: Repeat 3 More Times Until You Have a Pentagon
Step 15: Cut the Pentagon Out
Step 16: Tape One Triangle Onto Each Side of the Pentagon
Make sure the tape is on the outside of the mold so it doesnt leave a mark. Also make sure that all of the triangles are facing the same way so when you twist the design it will twist and make a pentagonal prism. Do as shown onto all sides of the pentagon
Step 17: Tape the Remaining Half Squares As Shown
Make sure it isnt flush on, so that it makes a twisted form
Step 18: Repeat Again and Again Untill You Have a Core That Looks Somewhat Like This
Step 19: Put on Another Layer of Tape
It is recommended to put a layer of tape around the design so it doesn't flatten out when you put plaster in it
Step 20: Make a New Pentagon at Least 2 Centimeters Smaller
This is for the core.This means you repeat the steps from earlier to make a pyramid, but instead of making it 5cm per side make it 3cm per side
Step 21: Make a Mark at Half the Length of Your Pentagonal Side
Make a line of your choice as shown. This will impact the height of your core
Step 22: Connect the Top of Your Line to the 2 Sides of Your Horizontal Line to Make a Triangle
Step 23: Make 4 New Triangles That Have the Same Sized Base As the Side of Your Pentagon, in This Case 3cm
Make sure all 5 triangles are the same height
Step 24: Tape All of Your Triangles Onto Your Pentagon and Fold
Try putting tape onto the
