Description
This is a remix of the Bike CO₂ Holder designed to improve compatibility and functionality. The original model was intended to fit alongside a standard bottle cage, but this version has been narrowed to work with mounts that do not support a bottle cage.
In addition to resizing the profile, a threaded section has been added so a CO₂ inflator head can be securely screwed on and off. This prevents the inflator from rattling loose, while keeping both the cartridge and head neatly stored on your frame for quick access during rides.
This designed has been tested thoroughly on a downhill course, through rock gardens, drops, jumps, mud, puddles, you name it - never failed.
Design Modifications
Narrower Body: Slimmed down to mount in areas where a full bottle cage is not practical.
Threaded Connector: Modeled threads allow the inflator head to be attached directly for secure storage and fast deployment.
Strength & Durability: Printed in PETG with 100% infill to handle the torsional stress of repeated screwing/unscrewing of the inflator.
Print Instructions
Filament: PETG recommended (for durability, flex, and outdoor use).
Infill: 100% infill for maximum strength. Lower infill may cause thread stripping or cracking.
Layer Height: 0.2 mm or finer for better thread definition.
Perimeters/Walls: At least 4 perimeters to reinforce the threaded section.
Supports: May be required depending on orientation; orient the threaded side upwards if possible to reduce support use.
Cooling: Moderate cooling for PETG (avoid overcooling to prevent layer adhesion issues).
Installation & Use
Print and remove supports if applicable.
Mount the holder to your frame in place of or alongside existing mounts.
Insert CO₂ cartridges as with the original design.
Screw the inflator head onto the threaded piece until snug.
Test threading gently to ensure smooth fit — minor sanding or cleanup may help if print tolerances are tight.
Notes
PETG is recommended for UV and impact resistance. PLA may crack under torque. ABS or Nylon could be used for even higher durability but may require more advanced print settings.
The design is optimized for standard threaded CO₂ inflators. Check thread alignment before use.
If you experience tight threading, lightly sand the printed threads or chase them with a tap/die set of the matching size.
