The enclosure for Wemos D1 with DHT22 shield.

*EDIT (06/2020) - I've updated the lid to have better mounts, on the corners instead of middle of the edges. I'ts way better mount, holds better and does not rotate.

It's made from two parts - bottom and a lid. The bottom part provides a spacer so the wemos board fits nicely and usb charging cable fits exactly through the hole. The lid is simple and it's only put on top with no XY movement. It has a holes designed to let the air reach the sensor. Bottom part has also holes, to cool down the chip. NOTE that if you use such close setup - that you put DHT22 on top of the chip, you get false-high readings, because the chip heats up the air nearby. But when combined with deep-sleep and about 3 minutes of sleep time, readings are exact. Another note: the white overhang with a hole on DHT22 sensor must be removed in order to fit inside the enclosure. However, it's done easily.

Please, do share a photos of printed part, I'd love to see your results! :)
