The clamps are fully adjustable from basically none (allows insertion of the tube) to quite tight. The outer cap controls that. The spools run very smoothly, all unwinding resistance will completely depend on how much PTFE you use.

The resistance is extremely low (dependent on how much PTFE you use) and very even. The spools don't hang loose on the rod (which is aluminum shower rod), they have an insert customized to the spool so that it runs evenly on the rod and the spools don't hang here and there. There are free turning spacers between the spools to ensure they don't interfere with each other.

my first latest glowfil experiments... super quick but fun. Hard to photograph.

Among many other things, I’ve been making dry boxes.. the meter was moved outside through the box in the close up. Each box with 4 reels takes about 38 printed parts plus some shower rod and screws/nuts and silica gel. I’m going to have 3 boxes of ready to go filament. Probably won’t store PLA in there The PTFE can go all the way to the extruder (swap out the short piece for a long one). Humidity in the box is running 17%. I’ll need to add a shelf on the back of the machine stand to hold it. This should make things more reliable without worrying about humidity. We will see how it all works out.

I like the concept of the longer tubes. But I have a question: don't the red clamps pinch off the tube after some time? And how is unwinding resistance in this setup, compared to the standard spool holder?

I also like the concept. But ANY form of uneven resistance will ruin high resolution prints. Ive seen it time and time again. On all spool related printers. And seeing as i have been only doing 0.06 for the past 5odd years. As soon as i print on a loose roll i can see it on the model immediately. Halfway through the spool tends to be ok but not the start. They need to invent unloosening spools (or an added mechanism) before printing high res can benefit from these sort of concepts and developments in my opinion.
