I need a simple plastic enclosure for my PCB. I already have the PCB dimensions and will provide them. The enclosure must be designed based on these dimensions, so the PCB fits tight, without extra internal space. Requirements: PCB must sit close to the enclosure walls (no floating). Material: plastic (ABS or similar). Simple, functional design (no complex styling). This is a practical enclosure, mainly for fit and function, suitable for prototyping.
