The document summarizes the first prototype project of group NJT2C. It discusses the manufacturing process which includes injection molding, joining, assembly and decoration. It also describes CAD modifications made to the outer and inner tubes. Issues faced included parts not fitting due to design and material availability. Solutions involved modifying the CAD and using precise machines for assembly of smaller, high resolution parts. Process durations are provided for injection molding and assembly.

5. Part Information

6. 1. P: That it does not fit the part. It was designed not to look
at the materials available in the market.
S: we modified the CAD.
2. P: The materials in the markets is not available for assembly.
s: we modified them.
3. P:The operation is complicated and complex. Because
the parts is high resolution due to smaller parts.
S:We use precise machine.
Process Duration
Injection molding Ca. 10-15 s
Assembly ca. 1 hr
