23mm PCB Enclosure Design

I have a tiny round PCB that sits on two acrylic discs, all adding up to just 23 mm in diameter. I need a clean, practical enclosure that I can print myself in PLA. The part must have screw insert holes.

Please model the housing so the discs are protected yet still easy to slide in during assembly, keeping overall thickness to the functional minimum. Once complete, send me the native CAD file plus an error-free STL ready for slicing. A quick exploded view or screenshot showing how the pieces fit together will help me verify clearances before I hit “print.”
