The per meter tube looks like one of the sizse sold for Bowden tubes.

It is one and the same material, it's a PTFE tube ID/OD 2/4 mm. Alternatives are Capricorn tubes, which supposed to withstand higher temperatures.

PTFE has an advantage of low friction as well has temperature tolerance; thus ideal for Bowden tubes.  Apparently, Capricorn tubes are still PTFE.

Any idea where I can buy this? Everywhere I find it, it is 1.75mm.

@sabo It's designed for 1.75mm filament, the ID will still be large enough to work flawlessly.

@sabo Online 3D print webshops, online market places, Chinese selling platforms, etc. I get my tubes from AliExpress, cheap, but you need to wait a few weeks or months. 2/4 mm PTFE tube is very common, it shouldn't be hard to find it in your city/country (more expensive but fast). You shouldn't buy too tight tubes, but 1.9/4 will work also for 1.75 mm filament.

<p>I have a Monoprice Maker Select Plus.</p>
<p>It recently started having issues printing. It turns out that the small plastic tube that feeds the extruder with filament was completely clogged. I couldn't get any of the filament out so I need a new feeder tube. I can't find one specifically for this printer anywhere. Does anyone have any ideas?<img src="https://i.sstatic.net/SWFJg.jpg" alt="enter image description here" /></p>

Could you add a photograph? Is this tube inside the heat break or between extruder and hotend?

I just added a picture. It is a plastic tube that goes inside of the metal tube I circled.
