2" NPT cap for Maxbotix USB ultrasonic sensor (oil tank level readings)

cults3d

I found the Maxbotix ultrasonic sensors extremely effective for monitoring the level in our home heating oil tank, so I decided to create a custom solution that would replace my previous method of using a 2" NPT PVC pipe plug. This new approach eliminates the need for careful drilling and yields a more polished result. This project started as a 3D model from McMaster-Carr, which I modified to accommodate the Maxbotix USB sensor with a side port access for the USB cable. For more details on how I designed this custom solution, see "How I Designed This" below. In my previous projects, I've used the Maxbotix sensors with TTL serial output (MB1043), but they've since released a USB model that's much easier to work with, so I've adapted this design for use with the MB1443 USB sensor. Maxbotix offers several tutorials on using their sensors with a Raspberry Pi: * An older tutorial for serial sensors: Interfacing a Raspberry Pi with an ultrasonic sensor * A more current tutorial for USB sensors: Connect a Raspberry Pi Zero with an USB Ultrasonic Sensor Here's a video showing a time-lapse comparison of my data to the actual physical float level on the oil tank, demonstrating how well it matches up: https://www.youtube.com/watch?v=5Ic_27f4kBo
