I came up with this concept model using 123D Design in order to help me get the angles and dimensions for a Wishing Well I wanted to construct in my wood shop. I have included DWG and STP files as well for anyone interested in in working on the model or taking dimensions for their own project. The model is in mm and I did a scale of 1mm:1inch for the purposes of my prjoect in the woodshop.
