Abstract: Dynamically balanced molded blade assemblies may be formed. A face plate of a dynamically balanced molded blade assembly may have one or more openings and/or one or more protrusions so that the blade assembly is within acceptable balance tolerance when rotated by a motor shaft of a fluid moving device.

Abstract: A molded container may include a unitary base. The base may include projections designed to secure, support, position, and/or protect one or more objects held in the molded container. The projections may be spaced to allow access to objects held in the base. The projections may include ledges and/or lips. A molded container may include a lid. An inner surface of the lid may have protrusions to hold objects in place in the molded container. Closure portions of the lid may snap securely on the base. A lid may be attached to a base or removable. A separate lid may include guides to facilitate placement of the lid on the base. In an embodiment, a base of a molded container may fit in the lid of the molded container. A lid and/or a base of a molded container may be designed to allow stacking of two or more molded containers.
