A modular bracket and associated instrumentation case configuration is disclosed herein. The modular bracket may include a support member structured to receive a specific instrument and hold the instrument at a fixed position, and an attachment member to facilitate a releasable attachment to a mounting surface such as an instrument tray platform. The modular bracket is shaped to provide an indication of the instrument, to allow user identification of the instrument received by the support member. For example, the indication of the instrument may be provided in the modular bracket by the perimeter shape of the attachment member that resembles an outline of the instrument. A modular instrument case assembly including a tray and housing may provide a platform for modular placement of one or more modular brackets into a specific arrangement of instrumentation.
