Step 23Build the cube: straigthen the pins
In our opinion, a LED cube is a piece of art and should be perfectly symmetrical and straight. If you look at the LEDs in your template from the side, they are probably bent in some direction.
You want all the legs to point straight up, at a 90 degree angle from the template.
While looking at the template from the side, straighten all the legs. Then rotate the template 90 degrees, to view it from the other side, then do the same process.
You now have a perfect layer that is ready to be removed from the template.

Step 24Build the cube: bend the pins
In the LED cube columns, we want each LED to sit centered precisely above the LEDs below. The legs on the LEDs come out from the LED body half a millimeter or so from the edge. To make a solder joint, we have to bend the anode leg so that it touches the anode leg on the LED below.
Make a bend in the anode leg towards the cathode leg approximately 3mm from the end of the leg. This is enough for the leg to bend around the LED below and make contact with it's anode leg.
