I was building an air quality sensor and when I made a box for it I thought why not also make a box that can be used on other Arduino projects. This model is for the fore mentioned Air Quality Monitor but I have included a blank front for people to drill and mount their own displays and buttons. (Or modify in Tinkercad)
The front, which is also the internal part uses an M3 brass insert to fasten to the box.
The front and the box do not need supports if printed in the correct orientation.
Maybe you can publish/remix your own fronts for projects. Please add them to the comments/makes if you do.
The Air quality monitor I made uses an SGP40 and an AHT20 for temp and humidity and a 1.8" spi lcd screen.
The author marked this model as their own original creation.
