The STL is for a 3d printed lure that should be around 14 grams when finished and casts well, and sinks slowly in salt water. The lure sinks flat and will rattle when jerked.Peripheral parts required are 0.8mm stainless wire, lead, eyes roughly 4mm in diameter, some form of bead or ball bearing for the rattle, UV resin and paint.
Process:Note: make sure the lure is around 100mm long so the through wire will fit correctly
