Hygrometer Wall Bracket

I made this model to hold a hygrometer I purchased through ebay at link below.It's for the round model and has 40mm hole which is different than most of the others I've tried. The model will stand on it's open base, or can be mounted with screw on back. You can double stick also as there is room for a good size strip. https://www.ebay.com/itm/313798000955?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=gubuRXZKRey&sssrc=4429486&ssuid=AVBLMQJtRpm&var=&widget_ver=artemis&media=COPY
