40mm test disk

thingiverse

Print this disk without a top or bottom layer to see the infill patterns. So set your slicer to print 2 or 3 perimeters, and 0 top and bottom layers. When the prints are done you will understand the stiffness and strength of each of the infill patterns betterNOTE: for infill patterns that don't interconnect, specifically Concentric, you need to print a bottom layer
