Hi, its replacement of skimmer basket , redesigned for easier 3D printing. 

Top diameter 156mm, height 73mm. 

With supports can be printed in one piece, but I recommend to print it in two parts (bottom and the rest) and then glue it together. In this case no supports needed and you will reach much better quality. 

Printed from Prusament PETG, standart setup MK3+ (0,2mm, 15%)

update: use really good waterproof glue, or tightening strips works quite well
