I made a 'TEST YOUR 3D PRINTER! V2' with overhang curling up test

thingiverse

This is an unofficial and against the license remix (I'll take it down as needed) of the awesome 'Test your 3D printer! v2' (Test_your_3D_printer_v2_0.48mm-with-overhang-curling-up-test.stl) http://www.thingiverse.com/thing:1019228 model as the option to 'Remix It' is disabled and the 'I Made One' does not allow uploading models. My Printrbot Metal Simple (second-hang and my first 3D printer) would pass the test yet relatively simple prints would fail due to over-hangs curling up - so I have modified their model to include a test which seems to duplicate the warping I am experiencing. To those with the warping overhangs issue after my investigations I believe it's due to inadequate/uneven cooling with the stock fan, I am waiting for an upgrade (https://www.aliexpress.com/item/Free-Shipping-Nidec-D04XL-12T2G-4028-4CM-12V-0-29A-double-ball-1U-server-fan-C34957/990053197.html) and will update with results afterwards.
