Coupler Nut - Remix

Thank you so much to GunplaMark for starting such a spectacular community driven filament storage solution. While most of Mark's original models work great, I had quite a bit of difficulty making use of the original coupler nut. I didn't see any remix that improved on the design; so i made my own. My variant has 3 functional changes: improved threads that make printing and installation easier sacrificial bridge layer for easier printing smaller hole to prevent the ptfe tube from being pulled into the cereal box There are no special print settings although a nozzle diameter above .4mm might result in poor quality threads. Also, once the print is complete, simply use a drill or tweezers to remove the sacrificial bridging layer.
