The document summarizes the project first prototype for Group NJT2C. It involved injection molding, joining, and assembling many parts to create the initial model. The manufacturing process included cutting, pushing, joining, and decorating parts. CAD modifications were made to the outer and inner tubes. Problems encountered included parts not fitting due to design limitations and material availability. Solutions involved modifying the CAD and using precise machines for high resolution assembly of smaller parts.

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.
