Case for an electronic device and manufacturing methods for making a case

An accessory unit for an electronic device, the accessory unit comprising:

• a front flap comprising:
• a plurality of segments, and
• a first layer and a second layer separate from the first layer, the first layer and the second layer combining to 1) cover the plurality of segments and 2) fold in regions between the plurality of segments, the first layer and the second layer further defining an end region;
• and
• a rear cover coupled with the front flap at the end region to define a hinge, the rear cover comprising:
• a shell forming a sidewall and a recessed region configured to receive the electronic device, wherein the first layer covers the sidewall and the recessed region,
• a opening in the shell, and
• a rigid filler disposed within the opening and covered by the second layer such that a force exerted on the second layer is at least partially transferred to the rigid filler and to a button of the electronic device;
• and
• a lip mechanically disposed along a periphery of the shell and formed from a material more rigid than the shell, the lip configured to retain the electronic device within the recessed region of the shell, wherein the front flap is configurable between a closed configuration in which the front flap at least partially covers the opening to the recessed region and an open configuration in which the opening to the recessed region is at least partially uncovered.
