Double AMS Mount for Riser by maCyo42

This 3D-printable Double AMS Holder was designed to compactly mount a second AMS above the first AMS. This creates a clean and compact dual-AMS setup without requiring additional space next to the printer.

The holder was specifically developed and tested for the Riser remix by maCyo42. It enables the secure mounting of a second AMS above the existing AMS and optimally utilizes the available space above the printer.

Sufficient space remains between both AMS systems for maintenance work, access to filament spools, and improved air circulation. Both AMS units remain easily accessible at all times.

Special attention was paid to compatibility with the existing Riser system. The original mounting points of the Riser are not lost due to the Double AMS Holder. Instead, these were directly incorporated into the arms of the holder and re-integrated. This allows existing or future extensions to be mounted as usual.

The holder supports the original Bambu Lab AMS  

Since the construction is larger than the print volume of many printers, it consists of several individual parts. These are assembled and glued after printing.

Important note:
This model was exclusively tested with the Riser linked in the description. Compatibility with other Riser versions or future revisions has not been checked.

Features

• Designed for the linked Riser
• Space-saving mounting of a second AMS
• Free access to both AMS systems
• Improved air circulation between the AMS units
• Original mounting points of the Riser are retained
• Mounting points were directly integrated into the holder arms
• Existing extensions can still be used
• Stable construction for continuous operation
• Multi-part construction for broad printer compatibility
• Visually matching the Riser's design

Print recommendations

• Layer height: 0.20 mm
• Material: PETG recommended, PLA possible
• Infill: 15–20 %
• Supports: Partially required
• Post-processing: All parts must be glued

Note:
The version shown in the pictures was successfully printed in PLA. However, for higher temperature resistance and long-term stability, PETG is recommended.

Assembly

• Print all required parts
• Remove supports
• First dry-fit the parts and check for fit
• Then glue all connections
• Allow glue to fully cure
• Mount the holder on the Riser
• Place and align the second AMS
