# WEEK 3

Try different sizes of circles and holes

Based on my last experience, I changed the size of the circle, setting it to 25cm, and also changed the size of the hole to find the most suitable diameter, I tried 23cm and 24cm.

After printing, I can connect the module with this size and I found that there wasn't much difference between the two diameters, so I kept both dimensions in my model to deal with different situations.
