Replacement 3d printed school Easy-Read Digital Meter case

This is a design for a replacement case for a school Unilab Easy-Read Digital Meter that is commonly used in UK classrooms for science lessons. It helps repair units that have broken cases (cracks, broken screens, broken mounting supports, etc.). It replaces the sockets with readily available alternatives. The design also includes specification for a new laser cut acrylic screen. The case fixings are replaced with threaded inserts and M3 screws rather than the rather fragile plastic supports and self tapping screws of the original. The 3d printed lid now includes an integrated 9V PP3 battery holder.

The replacement case is a similar size to the original, but slightly simplified so that the rear battery panel is a flat printable piece rather than a bent metal one. Assembly instructions are included with links to components required and detailed wiring instructions.
