Is anyone familiar with the 3-D vehicles advertised on eBay? (See https://www.ebay.com/itm/WW1-1-32-Scale-Renault-FT-17-with-Trench-Tail-High-Quality-3D-Printed-Tank/183237289735) There are several in 1:32 and more in other scales that have possibilities, but they look rather rough around the edges and I'm not sure how hard it'd be to get a decent finish. Would appreciate your comments.
