# 50mm/sec w/ raft=2, 0.4diam (wrong!), density 20%: works but causes very rough edges
# 40mm/sec w/ raft=0, 0.4diam (wrong!), density 20%: fails; infill becomes too sparse
# 35mm/sec w/ raft=0, 0.4diam (wrong!), density 50%, honeycomb: works, corners are rough
# 25mm/sec w/ raft=0, 0.2diam, density 75%, rectilinear: fails; detached from bed
# 35mm/sec w/ raft=0, 0.2diam, density 75%, rectilinear, first-layer 0.2: works, but takes like 6 hours to print
# - 2.5mm thickness => needlessly thick; stiff
# - 160mm length => too short
# - 3/3.5/6.0mm overhang => too much (that amount of overhang can't be printed reliably)
