Bill Cutlers 305 Burr, modifiable

Yet another extended puzzle from Bill Cutler. This one of the easier ones. The pictures are from the small 5mm version.

Please keep in mind that Bill spend a lot work on it and thankfully did not patented it. Nevertheless you might want to sponsor him by buying some nice wood version:
