I needed a bracket to mount my 3d printer filament spools to the wall. I went online, called a few stores, but what I envisioned was quite unique. I could make something from pipes at Home Depot I figured...Instead I modeled my ideal bracket on the computer. It took 20 minutes and then I sent the file to my 3d printer. I had my bracket in my hands an hour later. A little sanding and polishing and I screwed to the wall.It cost me 75 cents in plastic and saved me and the planet of waste. It was also quite fun and I learned something. Now I am sharing it with you.
