Asthma Inhaler + Spacer
A homemade alternative to regular inhalers in the market, this inhaler features both functional and aesthetic advantages. The greatest differences are that it doesn't look like an inhaler, which grants discretion and confidence to users; and that the casing becomes a spacer (aerochamber) to facilitate inhalation.
Characteristics:
- Built-in spacer (aerochamber) that also works as casing
- Spacer clicks into place for both positions, as spacer and as casing
- Discreet and elegant
- Fully 3D printable
- Compatible with standard medicine canisters
- Available in various lengths (depending on canister)
- Improved version with ribs for a tighter fit of the canister, files named V3 and V5 (thanks to Thingiverse user robinsdl)
- Easy to clean/sterilize
Important Notes:
- This design is an alternative, not meant to replace or substitute manufactured medical devices, especially if their features are prescribed and mandated by the healthcare professional for specific objectives.
- I am aware that regular spacers are more than just a tube; they come in all sorts of shapes, sizes, and functions depending on the age of the user and their specific needs. Spacers typically have valves and a design made with TPU could simulate that, however, this design does not have this feature.
- The simplicity of this alternative was sufficient for the specific condition of the end-user who participated in the design. Note that this may not be sufficient for other patients.
This design is the result of direct collaboration between end-user and industrial designer. We are happy to share it with the 3D printing community for asthma patients who could find this useful:

Print instructions
- No supports
- Brims or raft suggested for enhanced adhesion to print bed. Because the contact surface is small, tall objects could wobble and come off the print bed.
- Print at the highest quality possible, this minimizes chances of gaps and smoothens the exterior as layer lines will be minimal.
- Recommended to print this with ESD certified filament. When using filaments without electrostatic protection, the medicine sticks to the walls of the spacer chamber, reducing the overall delivery of the medicine. Alternatively, you can reduce the electrostatic charge in a spacer device by washing it with ordinary household detergent (source), thanks @drewborg_1418920.
Use this at your own discretion, always consult with your health professional before using alternatives.
