'''Prologue'''
<font color="red">Note: This manual only applies to the 5-mm acrylic Prusa I3. We have another one that is 8-mm. </font>

As picture is much more helpful than words in assembly manual, so I use plenty of pictures and less word. 


Unfold the package and take all the parts out to check the condition of the items.
