I saw some great deals on silver badger hair knots over at Whipped Dog, and wanted to try to make a handle. I haven't used a lathe in a while, so I wasnt sure how good of I job I would be able to do, but then I remembered that I have access to a 3D printer through my University! For those of you who aren't familiar with 3D printers, they work essentially like an inkjet printer, but instead of ink they put down ABS plastic (the stuff legos are made of), and instead of just doing one pass they do hundreds to thousands. This allows them to build almost anything in 3D, 1 layer at a time. Using a brush I currently have as a model, I built a handle on my computer.
The only thing I have left to consider before I can print it is the hole for the knot to fit into. Since the hole is being printed and not crafted, I need to get it as close as possible to the right size from the start; I can't just craft it to fit. I guess I could try to drill it out, or widen it with a knife after the fact, but it would look nicer if it was printed correctly. I was wondering, how precise are the knot sizes? If I get a 22mm knot, how close will it actually be? Would I be safe making a 23mm hole for it to fit into, or do I want to try to get it tighter? I'm guessing the best way to go would be to buy the knot first, and fit the hole to it, right? Also, how deep is generally good for the hole? Any input is always appreciated!
