Housing for Nocemcu and HC-SR04 ultrasonic distance sensor

prusaprinters

<p>This is a housing for a NoceMCU v3 and an HC-SR04 ultrasonic distance sensor. The lid will stay on when held upside down, but it's easy to remove. I designed this together with my son as an introduction to 3D modeling.</p><h3>Print Settings</h3><p>&nbsp;</p><p><strong>Rafts:&nbsp;</strong></p><p>No</p><p><strong>Supports:</strong></p><p>No</p><p><strong>Resolution:&nbsp;</strong></p><p>0.2 mm</p><p><strong>Infill:</strong></p><p>25%</p><p><br>&nbsp;</p><p><strong>Notes:</strong></p><p>&nbsp;</p><p>I printed a previous version of this in PLA. The big round holes in the wall came out quite nicely without supports, with some cooling. Since that print, I added a hole for the USB cable and some suports for the HC-SR04 sensor.</p><p>Please note that there's not enough room to plug cables onto the HC-SR04's connectors, but it will work if you bend the pins a bit. Alternatively you can just solder the wires on. It's also designed for a NodeMCU without pin header, or with the pins sticking up, whichever you prefer.</p>
