Case for US-100

I noticed on thingiverse that there are no cases for the US-100. And due to the different dimensions, the HS-SR04 will not fit into this case. And US-100 will not fit into others. Ordinary, ugly, but practical.

This is the first option. There is a non-threaded hole with a diameter of 3 mm.

There is a second option. There is a threaded hole with a diameter of 4 mm.
