The file 'Standing Owl With Flat Bottom Layer 3D Printer Model' is (stl) file type, size is 2.4MB.
The original model had some vertices and faces below the first flat layer, leading to the first layer flat not being well supported. I killed vertices and faces lower than 0.25mm and closed the hole in Meshlab and repaired the stl with netfabb for sanity.
