There are some other good contributions elsewhere on how to build your own UV curing chamber. I settled on a 3.5 qt. plastic tub wrapped with a 5m UV LED string, wrapped with foil, then wrapped with tape to hold it all together:
I got the tub here: http://www.containerstore.com/s/kitchen/food-storage/canisters/click-clack-cubes-with-white-lids/123d?productId=10029681
I got the LED string here: Amazon.com
A 1A 12V power brick runs the LED string. Total cost was about $40 and one hour to assemble. It stays cool enough to leave parts in indefinitely, although less than an hour is usually sufficient.
I added a 40mm fan later, to gently dry parts that just came out of the alcohol bath. The whole system is watertight, so I can UV cure immersed in water if needed
