Proto PCB enclosure

thingiverse

I needed a case for my small prototype PCB project, and what better option than one similar to this:http://www.ebay.com/itm/10Pcs-5-x-7-cm-DIY-Prototype-Paper-PCB-fr4-Universal-Board-prototyping-pcb-kit-/181846671646? I found out that the description mentioned it being 50x70 mm, but my board was actually 51x71 mm - which is what this case is designed for. The PCB slides smoothly into place via a slot on each side of the enclosure, fitting snugly. There's a comfortable 4 mm of space underneath the board, allowing plenty of room for pins and wiring. Meanwhile, there's 18 mm of space above the board, providing enough clearance to mount an Arduino nano (or micro, NodeMCU, etc) on a pin header. I designed not one, not two, but three different cases and three different lids for them. The main difference between each case is the amount of ventilation holes - a crucial factor in any design project. In contrast, the lids have distinct variations: one features no holes at all, another boasts a single slot or groove for accommodating cables, while the third has a convenient hole designed specifically to accommodate a USB connector when paired with an Arduino. **Print Settings** Rafts:** Irrelevant details don't concern me. Supports: Likewise, supports are unnecessary. **Notes**: To optimize print results, I positioned my cases on their high edge. By doing so, I avoided the need for any supporting material - it was that straightforward!
