Overview of parts and approx. costs

Stabilized membrane pump

Membrane pump (~$160) - here (TBD – cheaper solution may be available soon)

A: Upper Case (3D Printed)

B: Lower Case(3D Printed)

C: Intake manifold(3D Printed)

D: LED/Sensor holder(3D Printed)

E: LED/Sensor holder(3D Printed)
Print on any 3d printer or send to any service provider. Use black filament / resin. If possible, use flex filament or mix resin with flex resin. 200g Resin / FDM ~ $5-$10
- 3D printing service is more expansive (~$100)

F: bcMeter 12V or 5V - (find gerber files for PCB fabrication on bcmeter.org) ~$25

bcMeter general purpose PCB for 12V and large pumps

bcMeter SMD PCB for 5V and smaller pumps

G: Components from mouser.com or anywhere else (~60) – mouser shopping cart or bill of material
