As I occasionally print Manual Multicolor and always print via PTFE Tubes out of Dryboxes, I place my Drybox on top of the Enclosure and need a way to guide the PTFE in. For me, coming via the top seems natural.
So, I designed this entry point for up to five PTFE Tubes.
This is my third iteration, now using another five larger diameter PTFE Tubes (5mm/6mm ID/OD) to guide the PTFE tubes between my Drybox and the printhead as this drastically reduces drag and eliminates some issues I had before where the Filament Tubes could catch on something, or lowering z axis needed you to assist if to much of the Tube was outside of the enclosure.
It should be quite straightforward; no support is needed, and nothing is hard to print. I used Prusament PETG and a 0.4mm nozzle.
Print as many Plugs for unused holes as you want.
You need a couple of centimeters of a 5/6mm ID/OD PTFE tube like this from Amazon Germany https://www.amazon.de/DMiotech-Schl%C3%A4uche-Schlauch-Isolierrohr-3D-Drucker-Filament/dp/B0C7QJ4PV7/ref=sr_1_1?keywords=PTFE+6mm+5mm&qid=1707040441&sr=8-1
