Hi All,
im looking for engineer to help me to build a 3D prototype of
SmartPhone Bluetooth Detachable Printer

- Printer width should be 4cm
- Speed: 15 LPS (Line Per Second)
- Should be Open/Close to replace Rolls
- Should have a cutter to cut the recepit
- Should be Connected through Bluetooth with the smartphone
- Should be Detachable to the smartphone, same as attached photo
- Should have a button to press to connect to smartphone bluetooth
- Should have a light indicator, if light not stable means not connected if stable means connected to device bluetooth

So we need expert in printer to provide us with the prototype so we can contact our manufacturers to prepare us samples.
