I printed the Single Track Spool Holder by Walter Hsiao. I loved the design, but it didn't work for smaller spools like Taulman Nylon comes on. So I modeled this up in solidworks based on his design as inspiration. I love all of Walters work. He has an elegant and simple design style that I wish I could replicated... he is truly talented. I have the original model included here in Solidworks 2017, as well as stl, step, and fusion360.
