Filament Bin Holders

thingiverse

I started working on this simple little project after collecting a substantial amount of filament for my printer. As I accumulated more material, I began to notice problems with switching between different filaments and colors, which resulted in wasted time, dust buildup, and moisture concerns. To solve these issues, I came up with the design you see here. So far, it has resolved all the aforementioned problems and I genuinely hope it can do the same for you. I used PVC pipe as the main support structure, but it doesn't work well with filament spools that have smaller diameter holes, so I plan to modify this design in the near future. The PVC pipe has an outer diameter of 42.3mm and an inner diameter of 33.8mm. Twelve to twenty-four 1" machine screws were used to attach the holders to the sides of the bin. To minimize dust buildup, I attached a threaded filament dust filter (available on Thingiverse - http://www.thingiverse.com/thing:497764) to the bin via a 3/4" hole saw as shown in the photo, and desiccant was placed at the bottom of the bin. Note that I plan to add more filters outside my bin for three to four spools, but haven't had the chance yet due to other commitments. Print Settings Printer: XYZ Da Vinci Pro Rafts: No Supports: No Resolution: 0.2mm Infill: At least 30% for added durability Post-Printing Possible Acetone Option I smoothed out the objects after printing, which also helped improve layer cohesion. This step is optional and only necessary if you're a perfectionist like me. How I Designed This Simple Tinkercad Design It's just a few basic shapes placed together with the hole function to remove unwanted areas. Yes, it's incredibly simple and not exactly rocket science - but hey, it works!
