TEVO Tornado/20x20 Extrusion Filament Holder 3

cults3d

Here's my third filament spool holder I designed for my TEVO Tornado! This spool holder fits snugly into the 20x20 aluminum extrusion on top of the 3D printer frame and can be attached without disassembling the frame. It also includes a filament guide arm that keeps the filament from touching the greasy z-rod as it's pulled into the extruder. The design utilizes minimal-ish filament through a truss structure. I was hoping this spool holder wouldn't require a long printing time, but no such luck! It takes approximately 13-19 hours to print, depending on your print settings. However, consider it a great opportunity to test your printer's long-printing capabilities! This design also looks pretty cool, if I do say so myself. While I haven't tested it on other printers, this spool holder can likely be used on all other printers with 20x20 aluminum extrusion like the TEVO Tornado or printers that have other types of extrusions like 20x40. To determine if the filament holder is compatible with your printer, I've uploaded a quick and easy-to-print test piece that will tell you whether it can be mounted on your printer. You'll also find a version of the filament holder without the filament guide arm in case you don't need it. To mount the filament holder, angle it backwards so that the larger hook fits into the top part of the extrusion. Then smoothly position the filament holder vertically while slightly pulling up until you hear a noticeable click. This is the secondary hook snapping into place that prevents the holder from falling backwards if it's accidentally nudged that way. You shouldn't need to apply much force if you're slightly lifting up the filament holder as you rotate it into place. Make sure to read the printing instructions below carefully.
