Step 5: Cut the PVC
Be aware that you will have to do some math.... ooh. Shocker.
A caliper can be very helpful for finding all of the correct dimensions. When I created the cube, my measurements were pretty funky because PVC fittings vary in length so, in your best inetrest, I have left my measurements off.
The important thing is that the total for each side ends up the same so that the pieces fit together to make the cube.
