I tried acupuncture needles and garbage ties - both were too fat. Wires off a highly specific metal brush might work, but I would need a link to this particular brush to verify.
hypodermic needles - as they are hollow (so stiff) and you can order the bore size you want. - ebay has a few sellers.
I now own an Olssen block with 4 nozzle sizes (0.4, 0.6, 0.8 and 1.0mm). I love it. Its how the next Ultimaker should be made by default.
It is how the UM2+ are made by default
- 1 month later...
Just pull out the PLA and cut off the end and push it back again and I have had no problems in a clogged nozzle

And hypodermic needles. They work well also. 28 gauge:

Anyone who orders anything from my store in the USA gets one of those for free (modified so that it can't be used for it's original purpose).
