About this 3D model

This case has a press fit top. You can screw the board in place, but it is not neccessary. The antenna is mounted besides the LAN port. Keep in in that the OPi Zero can get pretty hot. I included big ventilation holes, but an additional heatsink is recommended. (I use the OPi Zero with Octoprint + Webcam and get 60 to 70°C in the case without heatsink under Armbian, never had a problem so far)
