That looks like Capricorn tubing. It’s got a 1.8mm, not 2mm, inner diameter.

I used to regularly run into cheap filament that varied up close to 1.8mm in diameter that would get jammed in the tubing.

When I did, tossing the roll was my only option.

Capricorn is great for reducing filament backlash and printing flex, but requires very consistent filament.

All Renaissance fairs are really medieval fairs.

They ended up called Renaissance Fairs because a radio ad exec in California thought it was a more broadly appealing name when the first one was held, and it stuck.
