Outdoor messenger bag installed on Brompton pig nose mount as a front bag conversion support backplate
Print Profile(1)

Description
The styles of dedicated Brompton front bags on the market always felt unattractive, so I chose this outdoor messenger bag shown in the pictures. I simply designed an installation support backplate that allows for non-destructive installation and quick removal. When needed, it can be directly fitted with a strap and carried away. The outdoor bag is lightweight, waterproof, and has a relatively large capacity, making it perfect for carrying basic cycling tools. Plus, it's affordable and matches well.
Note: This print file removes the top and bottom layers, and the infill pattern defaults to honeycomb. The material is PLA, mainly for aesthetic reasons. It can provide sufficient support; I've tested it with a bottle of water inside, and it might sway on bumpy roads but won't break. If you are concerned about strength, it is recommended to switch to PETG or other engineering filament and add top and bottom layers.
Installation also requires M5*25 screws and matching nuts.
