CFS filament buffer holder for Norco T riser

After receiving a lot of feedback, I decided to design a dedicated CFS filament buffer slot specifically for the exhaust system I created for the Norco T riser.

I've also created a filament buffer slot specifically for the Norco T risers without the exhaust vent.

Note: I haven’t printed or tested this version yet. If you give it a try, I’d really appreciate your feedback—let me know if any adjustments are needed!

You can use the same tube joiner holder included with the original version for this setup as well.

This add-on is only compatible with my custom exhaust setup for the Norco T riser. It allows the filament buffer to feed filament smoothly while maintaining a clean sweep bend, ensuring the tube curvature stays optimal and kink-free.

You can also use the same tube joiner included with the CFS upgrade kit, making installation even easier

What You Need:

1x M3 x 4 x 4.5 Screw Insert

1x M3 x 16mm Screw

2x Washers

Super Glue

Note: You’ll also need the custom Exhaust System for the Norco T Riser and the CFS Upgrade Kit I designed (for the filament buffer and tube joiner).

No glue or tape is required to install the buffer into the slot—it’s designed for a snug, secure fit right out of the printer.

To ensure everything works smoothly, I printed a Benchy positioned at the front-left corner of the printer bed—the area most likely to cause a tube kink due to the routing. This test confirmed that the filament feeds properly without any snagging or issues, even at the most extreme angles.

Note: If you’re concerned about the filament buffer slipping out, you can use two small wood screws to secure it in place using the pre-made holes in the buffer.
I personally didn’t need to screw mine in, as the fit was already firm—but this can vary depending on your print quality and tolerances.

If you like this design and find it helpful, I’d really appreciate a boost or a coffee to keep the ideas flowing! ☕️
