Hi! I was just tempted to buy an e3d spare part for my 3mm direct hotend to convert it into a bowden hotend. Just the heatsink is required for this. After some thinking and having some bowden snap-fits here I came to the conclusion that it would be very easy to cut a m4 thred into the e3d direct hotend´s heatsink and put the snap-fit on it. This way I could use it as a bowden hotend and I don´t see any reason why it should not work this way. Also, by removing the snap-fit again I still could use it as a direct hotend since the 3mm m4 thread would not really have any contact with the filament when I would use it directly on the extruder. What do you thinK? any reasons against this idea? https://reprap.org/forum/read.php?1,505710,505710#msg-505710 Mon, 13 Jul 2026 05:52:56 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,505710,506139#msg-506139 https://reprap.org/forum/read.php?1,505710,506139#msg-506139
But generally speaking.. why does the original e3d 3mm bowden hotend have a PTFE liner? The direct one does not have this "feature" or better said anti-feature since the idea is an all-metal hotend.

@ggherbaz: how does your printed part look like? something similar to this:
