Spool Holder 0.75 - 1" Extrusion Mount

thingiverse

For far too long, I had been without a spool holder. I wouldn't dare show what I was using as a makeshift holder - two cut pieces of plastic with a dowel mounted between them. This flimsy holder was creating headaches every time I needed to change spools. After some tinkering with Fusion 360, I created my first item with the software: a spool holder for my FLSUN i3 (I think they call it Model C - maybe someone will correct me). The one I printed had three major issues. First, the text was only on the back of the holder because I was using it on the right side. Second, the hole tolerances weren't very good, so the screw didn't fit correctly. I used the two screws and square nuts that I had on hand as I 3D printed a nice front mount from Thingiverse. Third, I thought the printer's extrusions were one inch, when in reality they are approximately three-quarters of an inch (2020) - still fits okay anyway. I corrected the text so it appears on both sides and increased the screw tolerances. Anyone who actually prints this design, if you could let me know whether the screws fit better, I'll update the text to reflect your feedback - thanks. The item likely requires supports as when printing on its side, the side screw bracket overhangs. The print came out great, and finally, a holder that isn't in the way. NOTES: 1) I now realize that the size hole might not be deep enough for a one-inch extrusion, and most people who might print this design may not want the text to say FLSUN, so I'll update the STL to add a one-inch specific version without the text. 2) The Flsun's three-quarter inch extrusion frame causes a one-eighth inch space between the side where the screw mounts. It works fine and is still solid as it's only for additional rigidity... but I will still update the model shortly to fix this.
