Poop Holder A1 / A1 Mini – Extruder Waste Bin

Poop Holder for Bambu Lab A1 and A1 Mini designed to collect purge waste directly from the extruder, keeping the printer clean and tidy during printing.

🔄 Update 2026 – Improved Supports (V3)

Thanks to community feedback, I have completely redesigned the internal supports.

The new supports are:

• more stable during printing
• much easier to remove
• removable in a few seconds with small pliers

The model has been tested multiple times with different filaments to ensure reliable printing and much easier support removal.

If you have printed a previous version and had difficulty with the supports, I recommend trying the new V3 print profile.

💩 Poop Holder for Bambu Lab A1 / A1 Mini (V2): collects purge waste directly on the extruder, keeping the printer clean and tidy.

💩 A1 / A1 Mini Poop Holder – Poop Bin (V2)

A compact bin to collect filament waste (“poop”) directly on the extruder of Bambu Lab A1 and A1 Mini.

👉 Result: less mess, cleaner print area, and tidily collected waste.

✅ Why you need it

During initial purge, color changes, brim/skirt etc... the “poop” ends up everywhere.
This accessory intercepts it at the source and collects it immediately.

⭐ Key Features

• Compatible with Bambu Lab A1 and A1 Mini
• Mounts on the extruder (without printer modifications)
• Stable during printing and does not interfere with movements
• Easy to remove and empty
• Clean design, integrated with Bambu style

🔄 Update V2 (November 2025)

The original model has been downloaded by thousands of makers and one feedback was recurring:

“The internal supports are too difficult to remove.”

Very fair feedback.
That's why I have completely redesigned the support geometry:

✅ stable during printing
✅ remove in a few seconds
✅ less risk of breakage
