It has an extra 0.3 mm on the top of the placement to correct the heigh deviation produced by the support contact. I printed it with an 0.2 mm Z distance on the supports.
I designed it with F3D and did it to add a temperature and humidity monitoring to this great mod, visual and through app. Is designed to minimice supports. I choose this model of hygrometer because it can be integrated in home assistant without the xiaomi's bt interface if your server/raspberry has a bt interface.
