large hex bolt and nut with square thread

thingiverse

In Bolt's Solidworks practice session, he created non-standard threads using a printed sample with its head flat on the build bed and shaft upward. The low-quality Replicator 2 settings were applied. A companion nut was also printed with identical low-quality settings but needs to be rotated about 10 degrees around its Y-axis to ensure its flat rests on the build table.
