Beautiful bathroom drainage cover that prevents hair from getting stuck on the grid making the bathroom cleaner. The cover is designed in a way that prevents long hair from getting stuck on it as they flow through it. Also the design is more beautiful than standard drainage covers as the blades are angled in a way that mostly prevents you from seeing the actual drain below. 
Two models are included; 131mm version has diameter of 131mm for the part that goes inside the drain and 148mm diameter for the top part that is left visible on the top and the 134mm version has diameter of 134mm for the part that goes inside the drain and 145mm diameter for the top part that is left visible on the top. The 131mm version is friction fit (as the original one for that drain) and the 134mm version mechanically attaches to the drain (as the original version). 
I printed mine in PLA with solid infill and it took about 130 grams of filament making these versions significantly cheaper than even the cheapest ones you can buy from a store.
