UNISMOOTH Filament Hanger

Model Overview & Print Notes

Summary This has been my go-to reel hanger for years when not using dry boxes. It eliminates z-banding caused by filament tension that lifts the extruder/gantry. Filament changes are super quick - whether you're changing the filament on the hanger or the hanger on the machine. ... and it is 100% reliable! Ball-bearing smoothness coupled with self-centering balance. Fine anti-unspooling brake. Suits reels from dia48mm-59mm that are up to 73mm wide. Plastic and cardboard spools are securely retained but slide on and off easily. Works with all commercial and Dept_9 reels (below). Perfect with the CLIP ON SPOOL HOLDER : https://www.thingiverse.com/thing:7042254 REQUIRED PARTS: Two 608 skate bearings. One M8x100 (5/16" x 4") bolt. Three M3x10 cap-screws. Nine coil springs - see pictures for details ( https://www.aliexpress.com/item/1005005402451548.html ). NOTES All parts are in the correct print orientation. The FINGERS are printed like this to align the layers with movement and strength; the supports come off easily and cleanly. The DRUM does not need supports; the bearing seats have crush-ribs for maximum tolerance. There are two versions of the unspooling brake: BRAKE-NUT: needs a push-fit M8 Nyloc nut; loosen it to finger-tightness with a #2 tap. BRAKE-NUDE: print-and-use as is; has a multi-lobular thread for the right amount of friction, preferably printed from PETG. When pushing the fingers into the drum, ensure the ends of the springs are trailing so they don't drag. Don't over tighten the three small screws that hold the cover on :-] Check out Dept_9's range of print-your-own filament reels: UniReel - the Rolls Royce: https://www.thingiverse.com/thing:6896875 Easy Refill Spool - Bambu Compatible - 2x one part flange: https://www.thingiverse.com/thing:7358401 Skeleton Spool Refill System - modular hubs and flanges: https://www.thingiverse.com/thing:7315046 Leftover Refill Spool Flange - small push-in flanges for cardboard refills: https://www.thingiverse.com/thing:7385975 Compact Loose Filament Spool - for loose leftovers & samples: https://www.thingiverse.com/thing:5634769 The Bitter End not quite a reel: a secure scrap-filament hanger for Enders: https://www.thingiverse.com/thing:7413168 Spool Ballast for AMS Rollers: https://www.thingiverse.com/thing:7320829 Spool Ballast PRUSA version : https://www.thingiverse.com/thing:7385413 General 3D printing accessories: Filament Desiccant System : https://www.thingiverse.com/thing:6938476 Stick-On Hygrometer Mount for filament storage boxes: https://www.thingiverse.com/thing:6929643 Clip-On Spool Roller for 2020 extrusions: https://www.thingiverse.com/thing:7318417 Early Warning Filament Low Sensor with a simple mechanical arm: https://www.thingiverse.com/thing:5761257 Clip-On Maintenance Stands for 2020 extrusions (Ender, etc.): https://www.thingiverse.com/thing:5736229 8mm Overspray Shield for lubing z-screws: https://www.thingiverse.com/thing:7400493 Bed Scraper PUCK https://www.thingiverse.com/thing:5779443 Wanhao i3 Spool Mount [Cocoon] for bigger reels: https://www.thingiverse.com/thing:5871827 Ender specific printing accessories: UniSmooth Filament Hanger quick 'n easy, smooth 'n reliable: https://www.thingiverse.com/thing:7419029 Clip-On Spool Holder that works with Ender brackets: https://www.thingiverse.com/thing:7042254 X-Gantry Chock Lock-Out secures extruder during maintenance: https://www.thingiverse.com/thing:7035515 Remote Viewing Filament Swatch perfect for USB cameras/PiCam: https://www.thingiverse.com/thing:5341389 BL Touch Cover/Mask tames the visual pollution: https://www.thingiverse.com/thing:5249031 Minimalist QR Cover for Ender 3 v2 : https://www.thingiverse.com/thing:7311447 Filament Sherpa for Ender 3 for clean and fast filament loading: https://www.thingiverse.com/thing:7075219 Ender 3 v2 Extruder Wiring Loom Hanger for plastic and metal extruders: https://www.thingiverse.com/thing:7034003 BTT Smart Filament Sensor Mount 18 versions: https://www.thingiverse.com/thing:5395137 Ender 3 v2 Dial Gauge Mount for bed levelling: https://www.thingiverse.com/thing:5213092 Ender 3 v2 Hidden OctoPi Mount : https://www.thingiverse.com/thing:5201485 And these two Dry Box systems: Using the Sistema 5.5L airtight container: https://www.thingiverse.com/thing:7218437 And the Sistema 3.5L container: https://www.thingiverse.com/thing:7349995 Check out more things from Department_Nine !
