Description
Update V1.1: There is a small change in the lid geometry. It should be easier to print out now!
NEW: By popular demand, there’s now a smaller version of this container that fits on the A1 Mini. Enjoy!
This is another container that mounts on the B-RAIL System. Designed to fit primarily on your bike’s vertical tube, it allows you to store bike repair essentials such as a multi-tool, tire levers, patch kit, spare tube, and CO₂ inflator.
For best results, use a 3 mm × 40 mm pin (DA024 from the Bambu store). If you prefer, you can also print the small pin in plastic — it’s included in the printing file.
About the B-RAIL System :
The B-RAIL System uses a mounting rail designed to fit any standard bottle cage mounts on your bike. It lets you attach a wide range of accessories and swap them out in seconds.
