Prusa XL nozzle brush holder

3D‑Printed Silicone Nozzle Brush Holder for Prusa XL

(Compatible with Bambu Lab A1 Mini Silicone Brush)

This 3D‑printed holder is designed to securely mount a Bambu Lab A1 Mini silicone nozzle brush and use it as an effective nozzle cleaning solution for the Prusa XL. It provides a reliable and repeatable way to remove filament residue and buildup from the nozzle before or during printing.

Product Description

The holder firmly retains the original Bambu Lab silicone brush while positioning it at an optimal height and angle for nozzle contact. The flexible silicone bristles allow gentle yet effective cleaning without damaging the nozzle, making it suitable for frequent use.

This solution is especially useful for multi‑tool or multi‑material setups on the Prusa XL, helping to reduce stringing, cross‑contamination, and nozzle buildup during tool changes or pre‑print routines.
