MakerFarm 8" Prusa i3v Enclosure

In the meantime, until you get enclosed, get one of those mylar space blankets. You know, the thin silver things that fold up the size of a soap bar. Then cut a piece of cardboard that is about 1" larger than your bed. Wrap a piece of that mylar around the cardboard and tape it well on the back side. While your bed is heating, just put that mylar board face down over the bed. It will reflect all that heat back and will it heat up much more quickly. Just make sure you are around when the printer starts so you can lift it off. It works really well for me.

You can also replace your heat bed transistor (RAMPS) with this one:

It has much lower Rds-on, so it runs cooler and the bed heats faster. Best $1.40 I've spent on my printer.
