I couldn't find a way to buy additional wall plates for our nanit, so I modeled a plate for hanging the monitor in other places. a future version will have threads in the middle so i can put the monitor on a tripod or something for travel. This is just my interpretation of a base plate to hang the monitor on the wall. I do not work for nanit or make any gurantees that this will work for yours. It's a free to use design that happens to hang on the wall and will hold a certain brand of monitor.
I've printed it in PLA and Nylon. both work great. you will need supports though. and you might have to trim the print to get a perfect fit with the monitor.
