and a planar contact surface configured to engage at least a portion of the receiving body, the contact surface extending between the first edge and the second edge; wherein a length of the constant contact protrusion is less than the length of the step; and wherein the constant contact protrusion is configured to maintain engagement of the snapping body and the receiving body; wherein, in the engaged position, the constant contact protrusion is configured to snap into a locking channel defined in an interior wall of the receiving body. ### Claim 2 (depends on 1) The system of claim 1, wherein the receiving body comprises: first and second side supports; first and second connecting walls disposed between the first and second side supports; and a passage defined by the first and second side supports and the first and second connecting walls. ### Claim 3 (depends on 2) The system of claim 2, wherein the passage is configured to receive at least a portion of the snapping body therethrough. ### Claim 4 (depends on 2) The system of claim 2, wherein the receiving body is configured to move along the constant contact protrusion, and wherein the constant contact protrusion snaps into the engaged position. ### Claim 5 (depends on 2) The system of claim 2, wherein the locking channel is configured to receive the constant contact protrusion of the snapping body. ### Claim 6 (depends on 5) The system of claim 5, wherein the receipt of the constant contact protrusion is configured to ensure an interior surface of the snapping body and the interior wall of the receiving body maintain the persistent contact over a dimensional range. ### Claim 7 (depends on 1) The system of claim 1, wherein the receiving body comprises predetermined dimensions configured to receive the constant contact protrusion. ### Claim 8 (depends on 1) The system of claim 1, wherein the snapping body is formed by injection molding. ### Claim 9 (depends on 1) The system of claim 1, wherein the constant contact protrusion is configured to at least one of prevent motion, resultant sound, or disconnection of the snapping body and the receiving body. ### Claim 10 (depends on 1) The system of claim 1, wherein the constant contact protrusion is configured to take a form comprising a ramp. ### Claim 11 (depends on 1) The system of claim 1, wherein the constant contact protrusion is configured to accommodate dimensional variations corresponding to the receiving body. ### Claim 12 (depends on 11) The system of claim 11, wherein the dimensional variations corresponding to at least one of the snapping body or the receiving body may be increased, decreased, scaled, or a combination thereof. ### Claim 13 (depends on 1) The system of claim 1, wherein the length of the constant contact protrusion is configured to increase a retention force. ### Claim 14 (depends on 1) The system of claim 1, wherein the length of the constant contact protrusion is configured to ensure a surface-to-surface contact between the step and a bottom surface of the receiving body. ### Claim 15 (depends on 14) The system of claim 14, wherein the snapping body and the receiving body are configured to move from the engaged position to a disengaged position responsive to a disengaging force. ### Claim 16 A cantilever system configured for tuneless operability, the cantilever system comprising: a receiving body comprising: first and second side supports; first and second connecting walls disposed between the first and second side supports; a passage defined by the first and second side supports and the first and second connecting walls; and an interior wall configured to define a locking channel; and a snapping body configured to ensure a persistent contact with the receiving body, the snapping body comprising: a supporting body; a step extending from the supporting body at a height along the supporting body, the step having a length extending between a first location along a length of the supporting body and a second location along the length of the supporting body, wherein the step is configured to lock the snapping body and the receiving body in an engaged position; and a constant contact protrusion extending into the step, the constant contact protrusion including: a first edge having a length extending along the length of the supporting body; a second edge having a length extending along the step between a first location along the length of the step and a second location along the length of the step; and a contact surface configured to engage at least a portion of the receiving body, the contact surface including a planar surface defined between the first edge and the second edge; wherein a length of the constant contact protrusion is less than the length of the step; and wherein the constant contact protrusion is configured to maintain engagement of the snapping body and the receiving body; wherein, in the engaged position, the constant contact protrusion is configured to snap into the locking channel in the interior wall of the receiving body. ### Claim 17 (depends on 16) The system of claim 16, wherein the constant contact protrusion is configured to ensure an interior surface of the snapping body and the interior wall of the receiving body maintain the persistent contact over a dimensional range. ### Claim 18 (depends on 16) The system of claim 16, wherein the constant contact protrusion is configured to at least one of prevent motion, resultant sound, or disconnection of the snapping body and the receiving body. ### Claim 19 (depends on 16) The system of claim 16, wherein the length of the constant contact protrusion is configured to increase a retention force. ### Claim 20 (depends on 16) The system of claim 16, wherein the length of the constant contact protrusion is configured to ensure a surface-to-surface contact between the step and a bottom surface of the receiving body. ### Claim 21 (depends on 20) The system of claim 20, wherein the snapping body and the receiving body are configured to move from the engaged position to a disengaged position responsive to a disengaging force. ### Claim 22 A cantilever system comprising: a receiving body comprising: an inner surface defining a passage; and a channel extending into and defined by at least a portion of the inner surface; and a snapping body comprising: a supporting body configured to be received within the passage of the receiving body; a step attached to and extending from the supporting body; and a contact protrusion comprising: a first edge extending along a portion of a length of the supporting body; a second edge extending along a portion of a length of the step;
