LACK enclosure filament feedthrough
thingiverse
Having assembled my LACK printer shelf (and eventually enclosure), I need to feed the filament from a drybox through the top of the shelf in a clean and tidy manner. This thing screws together though a 12.5mm (half inch) hole drilled through the top of the shelf, and tightened with a coin in the printed slots at the flanged end of both parts. The feedthrough accepts a 4mm ptfe tube to be inserted as a low friction guide for the filament. Filament PETG (or PLA) Temperature 230°/65°C Infill 100% Support none Adhesion Brim 5mm If you use Cura, set "Slicing Tolerance" to "Exclusive" for easier threading.
