I used a combination of wood burning kit, finely serrated knife, and tin snips. I found if I ran the wood burning tip around where I wanted the hole to thin the plastic first, then used the serrated knife to cut into the box, and then remove the knife without cutting, cutting the plastic only on the down stroke, it went pretty smoothly. Obviously it may be better to use more sophisticated cutting implements, but this did work for me without having to buy anything special since I already had all this stuff. I will say melting holes for zip ties was really nice with the wood burner. Of course ventilation is a must, and I don't have IKEA yet so this was on a large bin I got at Target. Any cracks I got I just used zip ties to stabilize them.
