Prusa Core One RMU Filament Buffer Mount for MMU3 MMU2S – Wedge Group RMU Holder

Custom RMU Filament Buffer Mount for Prusa Core One / Core One+Designed for the Wedge Group RMU Filament Management SystemThis custom CAD-designed mount securely attaches the RMU Filament Buffer by the Wedge Group to the Prusa Core One and Core One+ printers.The RMU system is widely considered one of the most reliable and durable filament management solutions available for Prusa MMU2S and MMU3 multi-material printing. While several mounts exist for the Prusa MK3S+ and MK4S+, I could not find a dedicated mount for the newer Core One platform—so I designed one.This mount positions the RMU buffer neatly along the side of the printer, providing clean filament routing and easy access when loading or changing filaments.Features• Custom CAD design specifically for Prusa Core One / Core One+• Compatible with the Wedge Group RMU Filament Buffer• Clean side-mount placement for efficient filament management• Quick installation using only two M3x10mm screws and two hex nuts• Printed in Prusa PETG Orange to match Prusa printer styling• Durable PETG construction for long-term reliabilityThe gray version shown is an early prototype used to clearly demonstrate the mount without the RMU buffer attached. Final production parts are printed in Prusa Orange PETG.Installation is simple and takes only a few minutes, making it an easy upgrade for anyone running a Prusa Core One with an MMU2S or MMU3 system.Mount only — RMU filament buffer and printer not included.
