February 2018

NOTICE: In an effort to continually improve our product, we recently began manufacturing our XS tubing with tighter tolerances. Due to this, more users are reporting filament jamming, higher friction, and things of that nature in the last couple of months. We believe many of these issues are being caused by out-of-spec filaments, but at the same time, we need to support the filaments people are using.

The bottom line is, if you have an issue with your tubing being too tight, please contact sales@captubes.com for a prompt free replacement.

We apologize for any inconvenience this has caused.
