Shallow 30 mm-deep purge chute and waste bin for the Elegoo Centauri Carbon 2. Prints in 48 minutes with zero supports and installs with the printer's existing screws — no extra hardware.

The slope runs all the way to the exit, so purges don't stall halfway down the way they do on other chutes.

Why this one

• Only 30 mm deep — fits on a shelf without pushing the printer forward
• No supports, no raft, no brim — 48 minute print for the chute (3 hours if the chute and bin are printed together)
• Uses the existing screws — access holes sized for the allen key in the CC2 toolkit
• Full-length slope — nothing stalls out on a flat section
• Fill-level slot in the bin — a glance tells you how full it is, like a reverse fuel gauge

Pairs with: CANVAS Spool Relocation Mounts

If you're running the CANVAS multi-color system, the stock mounts push spools 3 and 4 out past the back of the printer and blow up the footprint. I built these brackets for the same reason I built this chute — so the CC2 would actually fit on my shelf.

They pull spool 4 inward by 65 mm and spool 3 by 90 mm, reusing the hardware from the mounts you're replacing. Run both and you get a CC2 that stays shallow front and back.

Which files do I need?

Print one chute and one bin. The same bin works with either chute — pick the width you want. Width is how far they stick out behind the printer.

• 30 mm wide chute (original) — RndmCC2ChuteV5 + RndmCC2BinV5
• 40 mm wide chute (by request) — RndmChuteV7_40Wide + RndmCC2BinV5

Updated April 2, 2026 — current 3MF and STL files are attached below.

Print settings

• 3 walls at 0.5 mm wall thickness — makes the 2 mm chute walls solid
• No supports, no raft, no brim
• Cubic infill, or any 3D-oriented pattern, since this prints at an angle

Printed it?

Drop a comment and let me know what bin you paired it with — I'm collecting sizes that fit. A like helps other CC2 owners find this too.
