This is a 3D printed adapter that allows you to convert virtually any bag into a Brompton compatible bag.
This is a 3D printed adapter that allows you to convert virtually any bag into a Brompton compatible bag.
This adapter, printed with PETG (100% infill), is very sturdy.
It has been tested to endure a loading of 5kg over a long period of time.
The product will come with 4 sets of screws and 2 zip ties.
You can use screws or zip ties to mount the adapter on your bag.
For larger bags, I recommend putting a wooden board or L-shaped book shelf inside the bag as a support.
To avoid interference of the bag with the front reflector or light (if any), the adapter is better mounted at the bottom of your bag (aligned to the bottom edge).
Here is an example of conversion
