File: Shaft Couplings Straight.STLName: Shaft Coupling - Metric - StraightMaterial: 18.17 grams ( 0.04 lbs) Infill = 12%Size: 98.2 mm (3.866") x 21.76 mm (.857") x 30 mm (1.181")Resolution: 0.20mmLayers: 156 layers  Rafts: Yes  Supports: NoPrint Time: 2 hr 19 minFunction:  Prints a set of four couplings to connect 3mm, 4mm, 5mm, and 6mm shafts together.  Each couple requires two M3 x 12 screws and M3 nuts to squeeze each end of the coupling to its shaft.  If you don't need all four, simply print the size you need.  These couplings will take a surprising amount of axial misalignment inclduing offset and angular.  Each end of the coupling has the size engraved into the surface.
