This is a springboard from my earlier tutorial here:

Tea Candle Design (3D Print)
https://www.instructables.com/id/Tea-Candle-Design-...

There are numerous instructables on this.

This is just yet another path to the same end.

I took a tangent here and did something slightly different
from what I intended, so, as an additional bonus here,
I'll include an example of what I originally intended and
promised to deliver.

It's all connected.

This one's more Inkscape than Pepakura. But Pepakura
was helpful in setting up the fold flaps for the various
polyhedra I'll be using.

This one happens to be some nested Pentagons on a
square. Some design. Some cutting. Four sides.

More complicated to explain than it is to do. I'll try my
best to make it accessible and comprehensible and hopefully
you'll find it useful for more than just the finished product.

Pepakura not necessary for this Instructable.

Step 1: Basic Overview

Using a square template:

Create a Pentagon
Center it inside the square
Copy it, Rotate it, Resize it 3 or 4 times (your preference)
Group or Combine the end result
Print. Cut. Assemble.

Enjoy.

Step 2: Unzip and Load the File We'll Be Working With.

Open the attached zip file.

Open Inkscape and open "squares.svg".

(There's three files: Squares, Pentagons, Hexagons.
They're all formatted the same.)

Step 3: Managing Layers in Inkscape

Already done.

For your convenience.

Step 4: Create a Pentagon

I've included a gif to help with this process.

Make sure you've selected Polygon and not Star.

Make sure the Polygon is set to 5 sides.

Step 5: Creating a Pentagon - Animated Gif

Simple Process.

Create the Pentagon on the "Design" layer.

Use the left mouse button to click, drag, resize, move.

Use the "handle" (white circle) on the polygon to rotate
and resize the pentagon.

Step 6: Adjust the Stroke Thickness

Set the width of the stroke to about 15 pixels.

This is going to be cut out.

I generally set it thick as a margin against error.

Step 7: Align the Pentagon to the Squares Template

Clicking on Align and Distribute in the Objects
Menu opens a settings window on the right
as you'll see.

Included in the SVG, for your reference here:

Create the Nested Pentagons

With the Pentagon you've created:

Left Click to Select the Pentagon

1) Ctrl-C = Copy

2) Ctrl-Alt-V = Paste in Place

3) Left Click on Pentagon to Switch Between Rotate / Shear and Resize

4) Ctrl Drag = Proportional Resize

5) Ctrl-Shift Drag = Proportional Resize around Center Point

6) Shift Drag = Resize Edges

Hold Left Mouse Button on object and Drag to Move,
Resize or Rotate (Cursor changes to Cross Cursor)

Ctrl-Z (Undo) is your friend

Step 8: Aligning the Pentagon - Almost Done

Basic Steps of Aligning the Pentagon to the Template.

Step 9: Create the Nested Pentagons - Animated Gif

More difficult to explain than to do.

Step 10: Last Step. Group or Combine the Nested Pentagons.

Animated Gif

Worth a thousand words?

Grouping simply lumps the objects together. They can still
be ungrouped.

Combining the objects merges them into one object.
After it's saved, they can't be separated.

Before it's saved, you can always undo (Ctrl-Z) your
change.
