NEMA 17 Three-Motor Storage Tray
A 146 x 62 x 12 mm bench or drawer tray that holds three spare NEMA 17 steppers upright on their backs, each in a 43.3 mm square pocket that fits the 42.3 mm motor body. The shafts stay pointing up and out of the way. A 24 mm push-up hole under each motor and finger notches in the walls make them easy to lift out, and a 9.5 mm trough along the front holds the M3 screws, pulleys and couplers that go with them.

Along the front are three 43 x 32 mm scooped bins for loose horns, horn screws and spline adapters.
