Here's mine - I took delivery of a Filco Tenkeyless (UK model, MX Browns) on Monday and couldn't wait to pull it apart. My only complaint about the keyboard is that it didn't come with a puller. This took all of 10 minutes to make - which is reflected in its, ahem, refreshingly rustic appearance...

Construction details as follows:
Copper wire - you'll find a ready supply of this behind any power outlet in your home. Make friends with your fuse box first. Your mileage (and your risk of a house fire or personal injury) may vary. I accept no responsibility.
The handle is made of Polymorph - low temperature thermoplastic. Before you start complaining, this is an essential geek household item - if you don't have any, head over to ebay and order some right now (it goes by various other names; Hand Moldable Plastic, InstaMorph, ShapeLock, Friendly Plastic, Polycaprolactone etc). Just dunk it in hot water, conform to the desired shape with your bare hands, and allow to cool (about 2 minutes).
I think the copper wire I used is a little stiffer than regular keycap pullers, so it also doubles up as a handy egg whisk. Other (polite) suggestions for alternative uses are welcome...
