This tank paper model is the A7V-U Tank (Prototype German tank 1918), this tank papercraft is designed by Thai Paperworks and from landships. The A7V-U was an attempt to improve the trench crossing ability of the A7V by using the basic A7V frame and engine fitted with rhomboidal tracks like the British tanks. However, although the hybrid design was feasible, it proved to be unstable and was abandoned after fairly brief trials. The original A7V-U is thought to have been scrapped before the end of WW1. There is another A7V tank paper model on the site: WWI A7V Tank Paper Model.
