Purpose: Design object with the highest weight to strength ratio

Step #1 - Designing the infill pattern of the parts to reduce the material usage

Length*width*depth is 30*30*20 mm 

Infill density should not exceed 30%

Step #2 - 3D parts drawing using Creo software 

Provide two different designs

Step #3 - 3D printing (1 sample per group) 

The thickness of fine features should be at least 0.8 mm

Step #4 - Conducting compressive test and calculating all related data from stress-strain curve

Started out wanting to create honeycombs

Pivoted to + and then X design pattern

From that spawn the idea for diamond shape to support the walls caving in

Triangles are the strongest shape to relieve tension and compression
