Disclosed are a method and apparatus devices for an acrylic display case wherein the two panels (walls or ceiling or even floor) are adjoined using substantially wedge-shaped (trapezoidal) fittings capable of easily snapping into slot cut-outs / notches in the acrylic panel walls (or ceiling or floor) before final screw-tightening. The wedge-shaped fittings are easily positioned (inserted by sliding-insertion, then push-snapped) into their receiving slots in their respective panel slots (before being screw-tightened from a screw coming from the perpendicular panel). The wedge-shaped fitting promotes “one direction insertion” and then ‘snaps into place’ in its panel slot due to the fitting's “substantially three layer (3-structure)” style shape. Each fitting has an inner (anchors inside the box) face section with a surface area slightly larger than its panel notch. This inner section is ultimately positioned inside the case, acting as an inner anchoring lip against the acrylic panel's inside wall (wall herein interchangeable with “panel, whether ceiling or side or floor). The fitting further comprises a tapered middle section that allows for easy sliding-insertion into the panel notch-slot, and then allows gentle pressing / pushing into place (until friction gives to the “snap” positioning). This seamless positioning is made possible due to the fitting's middle-section tapering. After insertion (smaller end of the wedge fitting is initially inserted into the wider end of the dovetail shaped slot), as the fitting is then pressed into its slot, the tapered middle structure is what allows the fitting to gently slide against the panel notch's edge until the fitting “snaps” into place when this friction is overcome. The fitting further comprises an outer face section which is substantially larger than its panel-slot. This fitting “outer face section” has the largest surface area of the fitting's three sections. Both the innermost and outermost “layers / structures” of the fitting function as “lip-rim anchors” to keep the fitting firmly in its panel-slot, while the trapezoidal “wedge shape” of the fitting allows efficient insertion and ultimately secure snap-placement.The remainder of the system comprises modular panels with optional cut-out slots, tabs, indentations and screw holes to build a wide variety of display cases.
