This model is an HO scale (1:87) model that represents a circular reception desk found in - for example - a hotel, a hospital, a savings and loan, a library, or as a sales counter in a shop or larger store. It was made as a detail component for HO scale building interiors for lighted or un-lighted buildings on an HO scale train layout or HO scale diorama. Multiple file formats in addition to the printable .stl file are included so that you can modify it in a CAD or 3d modeling program to suit your personal needs. This model is royalty free for commercial images but can not be offered for sale as a mass produced commercial product in either digital or physical form and / or placed on an online market place. If you are getting rid of your old train layout in a garage sale - and on it is a building containing this piece as a construction / decorative element - then that's fine - you may sell it, otherwise - this is a free resource for hobbyists and non-professional artists only. I will be posting this on my thingiverse page in the near future as well.
