How much nicer is it to have your guitar on show, rather than in a corner somewhere. Well this mount allows you to do just that (and brag that you've got a 3d printer too :p)
Try and get the outward facing 45degree angle to be lying flat for the build - this will give you a nice shiny outward facing face and make sure that the piece is stronger (plane of layers not parallel to main force)
Hope you enjoy... let me know if you make one :)
