The Washington Square Arch is a triumphal arch commemorating the 100th anniversary of George Washington's inauguration as the first President of the United States. Originally designed in 1889 as a temporary installation made of plaster, the arch's popularity among the residents of Washington Square led to the erection of a permanent stone arch in 1895 that still stands today.

The structure was designed by architect Stanford White. The various engravings and statues adorning the arch are the designs of multiple sculptors. The spandrels depicting the various seals of the city of New York and the United States were designed by Frederick MacMonnies. The eagles perched atop the arch's keystone are the work of Philip Martiny. Guarding the piers on the northern side of the arch are statues of George Washington. The Eastern pier's statue, sculpted by Hermon A. MacNeil, depicts George Washington as a military general. On the opposite pier, Alexander Stirling Calder's statue depicts Washington as President. The two statues, originally named George Wasington as Commander-in-Chief and George Washington as President, have been given the shorthand names of Washington at War and Washington at Peace.The marble arch stands proudly over Washington Square Park as the gateway to the Greenwich Village and a monumental bookend to the Southern terminus of Fifth Avenue. In the years since its completion, it has come to be the unofficial symbol of New York University, whose academic facilities occupy most of the buildings surrounding the park.

There are multiple ways to print this arch. You may print the structure in one piece (WashingtonSquareArchComplete.STL).There are also 4 separate files for printing the arch's 2 piers, bridge, and top (WSArchEastPier.STL, WSArchWestPier.STL, WSArchBridge.STL, WSArchTop.STL). If you print these pieces separately, it is recommended to print the bridge section upside-down for better accuracy. This second method of printing is recommended for printing with higher accuracy or for printing in a much larger scale. The model was designed to be printed at a scale of around 1:300. This corresponds to scaling up the model to between 300 and 400% in whatever slicing program you use.
