A stackable (interlocking plastic brick-style) Fiber optic component tray. It aims to replace Thorlabs BFCT for applications requiring stacks of fiber-optic splitters, WDMS, circulators, and similar on an optical table. Unlike the original part, it is stackable in both orientations.

Please mind that the interlocking plastic brick-style connection is strongly fabrication sensitive. Tolerances will cause variations in the force required separate components of a stack of trays.
