Zigbee CC2531 USB Stick Case with Antenna

thingiverse

This design is heavily inspired by this [earlier design](https://www.thingiverse.com/thing:3532598), except that it comes with antenna support. ### Design notes * I decided not to design grilles to avoid having dust entering the case. * Also the CC2531 does not produce that much heat during operation. I personally live in a tropical climate with temperatures averaging 31C and if that doesn't heat up the CC2531, I don't see how it can cause overheating issues in temperate climates. * The design will fit the CC2531 snugly IF your antenna is soldered flush to the edge of the board. There is some allowance for solder thickness at the bottom. ### Assumptions * In my CC2531, there are no solders at the bottom of the board except for 2 USB solders at the front and 3 antenna solders at the back, so this design makes these assumptions of the board geometry. ### Parts Requirements * 2x M2x8 or M2x10 screws ### Device reference * I got my CC2531 with antenna similar to this listing on Aliexpress: https://www.aliexpress.com/item/1005001999985901.html ### Print recommendations * This should print well with 0.2mm layer height. * Make sure your printer is well calibrated. * Test print with the top first to see if the USB hole fits. If it doesn't try scaling 1-2% up or down. * Print the top with the USB external side facing the print bed. Rotate before print!
