The document summarizes the second prototype of Project NJT2C. The first prototype had issues with the slide not being smooth and the puller not being beautiful. For the second prototype, the team changed the shape of the puller to make it easier to use and made it out of aluminum. They also designed a new locking mechanism to make the slide smoother by reducing friction. Dimensions and functions were improved from the first to second prototype.

1. Project second prototype
Group NJT2C

2. 1 It is slide not smooth.
2.The puller is not beautiful.
P.1
1.It is not smooth when pull out and push in.
2.The lock systems is not perfectly.
P.2
Problems

3. 1.We change shape of puller
and design for easy using .
2.The puller is made from aluminum.
1.It is more smoother
because we design
new mechanism lock system
to reduce friction.
