I created this model to display the testing samples I accumulated in my MEGR3152 Materials Testing Laboratory at UNC Charlotte.

There are three different files:
 

• Display_3 has three holes vertical holes for displaying your hardness samples. Most students only have 3 samples to display.
• Display_3_Text is the same as above, but with the text ‘MEGR 3152’ at the bottom.
• Display_4 has 4 vertical holes for displaying hardness samples. This is the file shown in the photo.
