Filament tube holder (Bowden style) for Flashforge Creator 3

thingiverse

Tired of the filament tube popping out the print head of your Creator 3? Do you get annoyed by that hard-to-press insert where the tube ends, or you've lost it? Do you want to reduce the scraping/scratching/noise of the tube in the transparent top cover? Sort it out once for all, with this dual-threaded nut that allows you to make use of common PTFE tubing (4mm OD, like the Capricorn, etc.) with the simple push-fit of the pneumatic connectors. This will also allow to make an extra long tubing for printing with Nylon or other materials that require a filament dryer while printing. The nut has an internal thread M10x1 for those common PC4 connectors (as used in the Creality Ender 3), and an OD of 16mm. Depending on your printer resolution, the internal M10 thread may result a bit stiff, so you may need to chase it with a suitable tap, alternatively a loose fit can be sorted with plumber's tape. Edit: I've now given a little taper to the start of the thread in the main nut, to give an easy start with the locknut.
