LEDs with short leads causing problems? Answered

So for Christmas i got a bunch of these leds from amazon and im making and led cube with them. the problem is the leads are so short i use copper wire to give some space for each LED. so for instance its    [Cathode]-----copper wire-----[Cathode]     . But as i solder one end of the copper to one cathode, it will melt the connection at the other end causing me to re-solder once it cools, sometimes it total luck that it stays.  So if you can understand this, does anyone have a more productive way to make this cube?  (and please dont say get LEDs with longer leads)

If you have a set of helping hands you can use them to hold the leads and pull heat from the new connections

The others have the main solution -- add a heatsink clip.

Another option is to pre-tin your copper wire and led leg so that when you go to join them you get them held together, and just barely touch the soldering iron and they should solder together near-instantly without heating the whole length.

Use an alligator clip or needle nose pliers between the joints to act as a heat sink.
