After running across two different patterns this month for making knitting spools from wood and nails, I had to make my own. I took MikeTitor's Thread Spool into Tinkercad and started tweaking. I added pegs and cleared out the center. The first version worked, but the pegs were to small and I popped one off almost immediately. For the second version I made the walls of the spool a little thicker, doubled the size of the pegs, and added an angle to the bottom of the pegs to make them a little sturdier. It's working so far!
