2017-12-12 Update: A new snap on filament guide is now available: https://www.thingiverse.com/thing:2710135 This is a 608 bearing based spool holder that snaps securely on to popular aluminum extrusions used by a variety of 3D printers. Parts for 2020, 2040 and 3030 extrusions have been included. Why I'm a big fan of this design (inspired by remix source): - Simply put a spool on or lift it off. No rods, screws, nuts, etc. - Easy to snap on, off or re-position as needed - Bearing based for smooth filament feeding - Ideal for direct drive extruders like the Titan Aero as the filament is fed from above I deliberately avoided adding notches to fit into the extrusion channels to avoid compatibility issues between v-slot and t-slot. This design also won't interfere with belts or cables in the channels. The complete kit requires: 4 x 608 Bearings (AliExpress, Ebay, Amazon) or take the bearings out of fidget spinners 2 x Spool Brackets for your extrusion dimensions 2 x Side pieces I designed these parts with tight tolerances: - 0.0mm on the bearing so it should be held securely in place with only finger pressure to mount it. - 0.1mm on the extrusion dimensions for a tight snap fit and minimal wobble. Although it should be a good fit, If you feel like it's a little loose: * Use glue. * User Ruwaa has a make listed here where they used nuts and bolts (great idea!): http://www.thingiverse.com/make:406961 It was designed in OnShape so anyone can modify/remix the parts or export them to another format from here:https://cad.onshape.com/documents/29eb71db69e1bb7318d53beb/w/42585bfe3de101322142941e/e/df372655fda7ed3c82d11cde If anyone wants a version for a different sized extrusion, just let me know in the comments. Please share your makes!
