Week 8 - Challenge 3 - Coin Holder Design

Challenge is to create a 2.5mm wall thickness plastic component from the given Class A surface.

Pictures of the Part produced by Close Surface.

Tree structure details below

Below the details of tooling creation. First a boundry was created to check the surface gaps and found no gaps. Then intersection curve was created as shown below and a point on the surface for axis also created. With this interesection curve as the reference two lines were drawn. The bisecting line of these two lines was created and named temporary axis1.

Similarly on the other side interesection curve was created. With reference of side wall lines two lines were created. Bisecting these two line new line was created which was named as temporary axis 2. Both the temporary axis merged and so one of the axis was used as final tooling axis.

Draft analysis with reference to the tooling axis at 3degree of Class A surface is as below.
