Over the last year I've developed an interest in burr puzzles. Mostly thanks to burrtools, because I'm too lazy to work on them without it You can see a bunch of them here:

Bram's burr puzzles

I highly recommend the rest of that site as well. It's a huge collection of burrs.

Sweet!


That's a great site. I have this one irl - http://www.asahi-net.or.jp/~rh5k-isn/Pu ... sibleBurr/. Great puzzle!

I like the swirls ones. Maybe someone could make these up and 3d print them (someone with access to a 3d printer for cheap/free) and send you some?

Wow. I really like those burr puzzles. They seem like some/many if not all of them will be challenging like many of the puzzles you design. Are you planning to make these in real life?
