About this 3D model

I have various holes in my house brickwork and have noticed small to tiny bees using them. Tanya Weaver http://www.girlmeetsbee.blogspot.co.uk/ mentioned these are solitary bees, and make homes in all sorts of places, this was my attempt to give them a nice place to live. It could do with a rain cover and maybe the entrance pointing 20 degrees down. Design by RichRap - www.richrap.com
