Qingping CO2 & Temp & RH Monitor is designed to be hanged on the wall with a provided hook. It's possible to place it on a flat surface out of the box, but then you don't have access to the USB-C port for charging and the screen may get unreadable if the device is below line of sight.
This stand is designed to be used with angled USB-C cables or straight ones with any generic angled adapter. It provides holes for routing cable to the left, right, or back of the stand. Moreover, there are legs added so you can stick adhesive rubber feet to stabilize the device. Designed to be printed upside-down without supports.
Printed with Hyper PLA-CF on Creality K1C at 0.16mm layers, but other materials should be fine as well. The rubber feet used are generic no-name with 10mm diameter and flat bottom (rounded one may cause the device to tip-over on higher angles). Tested USB-C adapters and cables are shown in photos.
