CC2531 Case with external antenna

thingiverse

This case is designed for an enhanced CC2531 zigbee sniffer that I use in my home automation system. The wireless connection is strong, but adding an external antenna still improves it significantly. The antenna used in the picture may be a bit too large, but it works perfectly fine as it was readily available at home. There's a similar case available online, but it can only be purchased and not downloaded for free. I decided to give back to the DIY open source community by designing my own case, which is free to use for everyone. 20190826: A new version 2 of the case without text was added as requested. No other changes were made except removing the font for easier printing. 20190923: After noticing that there are different types of CC2531 adapters available (I've ordered five of them in the past few months), I realized that some of them fit perfectly while others don't. To accommodate this, I need to create another version of the case that fits the "other" type. The main difference lies in the positioning of the USB connector relative to the PCB. 20191006: Two pictures were added showcasing a "good" version of the PCB - one where the print will fit perfectly and another "bad" version which won't fit at all. 20191020: A new version of the case was uploaded for the latest hardware with the shifted USB connector. The file is named "CC2531 Case v6 new Hardware v1.stl". I encourage users to test it out and provide feedback on how well it fits their hardware. For my own setup, it fit perfectly without requiring any scaling. 20191030: A text-free version of the case was added as per request. The filename is "CC2531 Case v6 new Hardware NO text v1.stl".
