the first platform defines a first slot having a longitudinally aligned central axis extending therethrough, a second slot having a longitudinally aligned central axis extending therethrough, and a first locking hole; a second platform; and the second platform defines a third slot having a longitudinally aligned central axis extending therethrough, a fourth slot having a longitudinally aligned central axis extending therethrough, and a second locking hole; wherein the longitudinally aligned central axis of the first slot is perpendicular to the longitudinally aligned central axis of the second slot; a bar having a first end and a second end; the bar comprises a flexible first cantilever having a first button proximate a first end and a flexible second cantilever having a second button proximate a second end, the first button sized and shaped to mate with the first locking hole when the first slot mates with the first end, and the second button sized and shaped to mate with the second locking hole when the second slot mates with the second end. ### Claim 2 (depends on 1) The kit according to claim 1 wherein the first locking hole is disposed at an intersection of the first and second slots. ### Claim 3 (depends on 1) The kit according to claim 1 wherein the second locking hole is disposed at an intersection of the third and fourth slots. ### Claim 4 (depends on 1) The kit according to claim 1 wherein the first slot is oriented at approximately 30 degrees with respect to a longitudinal central axis of the first platform. ### Claim 5 (depends on 1) The kit according to claim 1 wherein the second slot is oriented at approximately 60 degrees with respect to a longitudinal central axis of the first platform. ### Claim 6 (depends on 1) The kit according to claim 1 wherein the third slot is oriented at approximately 30 degrees with respect to a longitudinal central axis of the second platform. ### Claim 7 (depends on 1) The kit according to claim 1 wherein the fourth slot is oriented at approximately 60 degrees with respect to a longitudinal central axis of the second platform. ### Claim 8 (depends on 1) The kit according to claim 1 wherein the second slot has a greater length than the first slot. ### Claim 9 (depends on 1) The kit according to claim 1 wherein the fourth slot has a greater length than the third slot. ### Claim 10 (depends on 1) The kit according to claim 1 wherein the longitudinally aligned central axis of the third slot is oriented perpendicularly to the longitudinally aligned central axis of the fourth slot. ### Claim 11 (depends on 1) The kit according to claim 1 wherein the bar includes two discrete 15-degree bends. ### Claim 12 (depends on 1) The kit according to claim 1, wherein the first slot is sized and shaped to mate with the first end of the bar, so that when said slot mates with the first end, the first platform is fixedly attached to the bar with a first orientation relative to the bar. ### Claim 13 (depends on 12) The kit according to claim 12, wherein the first orientation is a 30-degree external rotation relative to a longitudinal anterior-posterior axis of the first platform. ### Claim 14 (depends on 1) The kit according to claim 1, wherein the second slot is sized and shaped to mate with the first end of the bar, so that when said slot mates with the first end, the first platform is fixedly attached to the bar with a second orientation relative to the bar. ### Claim 15 (depends on 14) The kit according to claim 14, wherein the second orientation is a 60-degree external rotation relative to a longitudinal anterior-posterior axis of the first platform. ### Claim 16 (depends on 1) The kit according to claim 1, wherein the third slot is sized and shaped to mate with the second end of the bar, so that when said slot mates with the second end, the second platform is fixedly attached to the bar with a first orientation relative to the bar. ### Claim 17 (depends on 16) The kit according to claim 16, wherein the first orientation is a 30-degree external rotation relative to a longitudinal anterior-posterior axis of the second platform. ### Claim 18 (depends on 1) The kit according to claim 1, wherein the fourth slot is sized and shaped to mate with the second end of the bar, so that when said slot mates with the second end, the second platform is fixedly attached to the bar with a second orientation relative to the bar. ### Claim 19 (depends on 18) The kit according to claim 18, wherein the second orientation is a 60-degree external rotation relative to a longitudinal anterior-posterior axis of the second platform.
