Filament Cleaning Clip

thingiverse

A long-standing problem with our FDM machines has been that filament often picks up dust or grime and jams, resulting in prints that aren't as clean as they could be. I quickly designed this solution in Fusion 360 and printed it out on our Form 2 so I can eventually create a silicone mold and cast it. The larger part is intended to stick to the back of your printer (or wherever works for you) using double-sided tape. The clip section is held together by four round magnets, each with a diameter of 4mm and a thickness of 1.5mm. These magnets are glued in place using two-part epoxy, while the clip attaches to the base section via two rectangular magnets measuring 6 x 4 x 2 mm. Once you've assembled everything, all you need is two small rectangles of foam or sponge for the holder sections, a bit of mineral oil, and you're ready to go. No more dust problems and nice, lubricated filament are now within your reach. Tolerances in this design are set a little wide for SLA machines but should be just right for FDM machines to print out without any issues. To construct this solution, you'll need the following magnets: Circular Magnets can be found at http://www.first4magnets.com/circular-disc-rod-magnets-c34/4mm-dia-x-1-5mm-thick-n42-neodymium-magnet-0-36kg-pull-p3805#ps_1-1816 Rectangular Magnets can be found at http://www.first4magnets.com/rectangular-magnets-c35/6-x-4-x-2mm-thick-45h-neodymium-magnet-0-75kg-pull-p3563#ps_1-2240 To print the parts, you'll need to create two filament holder sections for every filament line. If you want to attach your filament holder to the side of your printer, print one base section for each cleaning clip attached to it.
