Designed for the Brother XL6452.
Original manufacturer part number: X57370022 — flywheel for Brother household sewing machines.
Compatible with the following models:
• Brother Star 35, 45, 50, 55, 60, 65
• Brother PS3700, PS55, PS57
• Brother Boutique 27, Boutique 37

The model consists of two parts: the flywheel itself and a separate tab.
Print two tabs lying flat so that layer lines run parallel to the bend direction. After printing, press the tabs firmly into the slots on the flywheel.

The slots in the flywheel are precisely sized (5 mm) to fit the tabs tightly without adhesive. If needed, scale the tab down to 4.9 × 4.9 mm in your slicer (e.g., Orca Slicer) and secure it with plastic cement or solvent glue.

Printing instructions:
• Load the model into your slicer, repair the mesh (I'm not sure if it's necessary, but I always do this), separate the parts, and duplicate the tab to get two copies
• Material: PETG
• Walls: 3
• Standard settings recommended

A second version of the flywheel is included — created while practicing 3D modeling. You may prefer its design.
