Get the 3D files form below, you have version 1 which is the one from this video and version 2 which is smaller and better look. You will get a zip file. All parts are prepared for pint and you have indications which needs support or not. I've printed all PLA parts with 20% infill, 3 perimeters and 0.25mm layer height. Only the round cushins are printed with flexible, 10% infill and 3 perimeters. The rest are all PLA material. Then you could pass some sand paper and paint the parts if you want.
