Super simple prototype but if it works... Very cool idea!

This could be achieved by coiling up the space where the filament travels through

Yes, that's also what I already mentioned in the other comment...

"Unless you have a coil or something inside the tube heater so it spends longer time in there"

but as I also mentioned, pulling filamennt through a coil will also introduce significantly more resistance than pulling (or pushing if using bowden) it straight, which might be an issue at high speeds and cause under extrusion.

Sorry, I completely didn't read all of your comment. You're right about resistance but then again the filament won't need to touch the enclosing coil at a large surface. In the usual bowden tubes, you have a lot of contact surface between tube and filament but this would not need to be the case in the drying coil. In the end it would all depend on the application. I'm not interested in very high speed printing (yet) because my machines are all pretty slow :).
