This case is intended to be used with the Arylic Up2Stream Pro V3 + V4 (Multiroom Audio Receiver Board). Cover and base are held together by four M3x16 hex-screws (self tapping, no threaded inserts required). The board is sitting in between both parts. The IR-Receiver and the LEDs are accessible through small holes on the side.

The case features decor-elements, which are seperated from the two main bodies. You can use them to apply a custom (open) infill pattern/color/material to the case. Combine the parts in your slicer or use the included 3mf-file (setup for a Prusa MK4 in PrusaSlicer with mostly default settings). For the *_decor.stl chose no top and bottom layers.
