In one implementation, a custom feedback device comprises a shell housing having a first shell and a second shell. The shell housing opening extends between an outer surface of the first shell and an outer surface of the second shell. A plurality of protrusions extends between the first shell and the second shell, and at least one receiving area is defined by the plurality of protrusions between the first shell and the second shell. The receiving area is adapted to house a customized portion. ## Claims ### Claim 1 A custom feedback device comprising: a first shell having a first inner surface disposed opposite a first outer surface, the first inner surface including at least one of a ridge or a groove; a first shell opening defined in the first shell and extending through the first shell; a first plurality of protrusions extending from the first inner surface, the first plurality of protrusions including a first coupler; a first plurality of receivers defined in the first inner surface; a second shell having a second inner surface disposed opposite a second outer surface; a second shell opening defined in the second shell and extending through the second shell; a second plurality of protrusions extending from the second inner surface, each of the second plurality of protrusions including a second coupler; a second plurality of receivers defined in the second inner surface, the first shell releasably engageable to the second shell to form a shell housing based upon a connection between the first plurality of protrusions with the second plurality of receivers and the second plurality of protrusions with the first plurality of receivers, with the first coupler of each of the first plurality of protrusions being releasably engageable to a respective second receiver of the second plurality of receivers and the second coupler of each of the second plurality of protrusions being releasably engageable to a respective first receiver of the first plurality of receivers, the connection: forming a receiving area oriented around a side of the shell housing and defined between the first shell and the second shell; and aligning the first shell opening and the second shell opening to form an opening of space extending through a central axis of the shell housing; and a customized portion of a plurality of customized portions adapted to be housed at the receiving area based on a feature that mates with the at least one of the ridge or the groove of the first shell based on the feature having a shape complementary to the at least one of the ridge or the groove, wherein: the customized portion is retained in the receiving area when the first shell and the second shell are engaged, and the customized portion is interchangeable with a second customized portion when the first shell and the second shell are disengaged, the first shell and the second shell being configured to disengage using a force that overcomes the connection. ### Claim 2 (depends on 1) The custom feedback device of claim 1, wherein the receiving area is an insert area and the customized portion is an insert. ### Claim 3 (depends on 1) The custom feedback device of claim 1, wherein the receiving area is a corner area and the customized portion is a corner. ### Claim 4 (depends on 1) The custom feedback device of claim 1, wherein the customized portion is interchangeable upon a release of the first shell from the second shell. ### Claim 5 (depends on 1) The custom feedback device of claim 1, wherein the customized portion is removable upon a release of the first shell from the second shell. ### Claim 6 (depends on 1) The custom feedback device of claim 1, wherein the customized portion is accessible when housed at the receiving area. ### Claim 7 (depends on 1) The custom feedback device of claim 1, wherein a liner is disposed within the opening. ### Claim 8 (depends on 1) The custom feedback device of claim 1, wherein the connection is a snap-fit connection. ### Claim 9 (depends on 1) The custom feedback device of claim 1, wherein the first inner surface and the second inner surface each include an insert receiver defined in the receiving area to releasably engage the customized portion. ### Claim 10 (depends on 1) The custom feedback device of claim 1, wherein a post extends from each of the first inner surface and the second inner surface within the receiving area to releasable engage the customized portion. ### Claim 11 (depends on 1) The custom feedback device of claim 1, wherein the customized portion includes one or more customized feedback stimuli. ### Claim 12 (depends on 11) The custom feedback device of claim 11, wherein the customized feedback stimuli includes at least one feedback surface. ### Claim 13 (depends on 1) The custom feedback device of claim 1, wherein the customized portion is accessible from an exterior of the shell housing. ### Claim 14 (depends on 1) The custom feedback device of claim 1, wherein at least one of the first outer surface or the second outer surface includes customized feedback stimuli. ### Claim 15 A custom feedback device comprising: a first shell having a first inner surface disposed opposite a first outer surface, the first inner surface including at least one of a ridge or a groove; a first shell opening defined in the first shell and extending through the first shell; a first protrusion extending from the first inner surface; a first receiver defined in the first inner surface; a second shell having a second inner surface disposed opposite a second outer surface; a second shell opening defined in the second shell and extending through the second shell; a second protrusion extending from the second inner surface; a second receiver defined in the second inner surface, the first shell releasably engageable to the second shell to form a shell housing based upon a connection between the first protrusion with the second receiver and the second protrusion with the first receiver, the connection: forming a horizontally oriented receiving area positioned around a side of the shell housing and defined between the first shell and the second shell; and aligning the first shell opening and the second shell opening to form a vertically oriented opening of space extending through a center of the shell housing; and a customized portion of a plurality of customized portions adapted to be housed at the receiving area based on a feature that mates with the at least one of the ridge or the groove of the first shell based on the feature having a shape complementary to the at least one of the ridge or the groove, wherein: the customized portion is retained in the receiving area when the first shell and the second shell are engaged, and the customized portion is interchangeable with a second customized portion when the first shell and the second shell are disengaged, the first shell and the second shell being configured to disengage using on a force that overcomes the connection.
