Fancy ergonomic footrest (fully 3D printed, single piece)

This is a fully 3D printable ergonomic footrest. 
It's not a hard print, but it's long and has a few caveats: 

-You'll need to print it from ABS, ASA, PETG or at least PLA plus\pro
-It has one quite aggressive overhang, so make sure that you have adequate settings
-Printer enclosure is highly recommended

The size is 150x200x260. It should print okay on most printers, but maybe you'll need to adjust width\height. If you have printer with larger print volume, scaling it to 150x200x300 is preferred, because now it's quite small.
