Wemos / Lolin D1 Mini + DHT22 sensor case

It has come to my attention that the variability in width of the Wemos boards can indeed cause a problem with the friction fit. My initial batch of boards measured approximately 25.55mm wide, which fits nicely within the 25.60mm space of this Thing. However, a more recent batch of boards I've received are all roughly 25.85mm wide, so they will require enlarging the Thing. If you have digital calipers, I highly recommend checking your boards before printing! I made some modifications to the design for the newer version of the D1 Mini (v3.0.0) that I possess. I relocated the hole for the reset button to the opposite side and adjusted the USB cutout slightly. Additionally, I relaxed the tolerance on the Wemos board while tightening the tolerance on the sensor, making corresponding changes to the lid. If you print the lid in a translucent material, you can observe the built-in LED through it. You may need to experiment with scale settings to achieve perfect fit and tolerances with your printer. I settled for a 100.5% scale setting for the lid to attain the desired fit. I inserted the Wemos board into deep sleep for 60 seconds between readings, so there is no risk of heat buildup affecting temperature readings.
