Twisted Pentagonal Prism Pencil Holder

This is a guide on how to make one

Glue a Blank A4 Paper Onto High Impact Polystyrene

Put the paper onto the corner as shown

Set a Protractor As Shown and Make a Mark at 70º

Draw a 15cm Long Vertical Line

Make sure it lines up with the Mark your protractor made

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.

Make a 5cm Measurement As Shown

Start at the top of your vertical line

Make Another Mark Angled at 70 Degrees, Starting From the 5cm Mark You Made

This will help make your angled rectangle

Make Another Line From the Mark As Shown

This will complete 1 angled rectangle

Make 4 More Angled Rectangles With the Same Measurements

Cut Out All of Your Angled Rectangles

Make a Diagonal Line As Shown on All of the Recrangles

Make sure all the lines are going the same direction

Cut Across the Diagonal Line

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

Line Up a Protractor at 108º and Make Another Line

Set up as shown.

Repeat 3 More Times Until You Have a Pentagon

Cut the Pentagon Out

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

Tape the Remaining Half Squares As Shown

Make sure it isnt flush on, so that it makes a twisted form

Repeat Again and Again Untill You Have a Core That Looks Somewhat Like This

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

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

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

Connect the Top of Your Line to the 2 Sides of Your Horizontal Line to Make a Triangle

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

Tape All of Your Triangles Onto Your Pentagon and Fold

Try putting tape onto the
