Sink Strainer for the kitchen sink

This is a simple plug for the kitchen sink. Works for a 80mm hole. It works best if it is printed in ABS or PETG plastic. PLA tends to distort quicker when subjected to hot water. We have used the design for almost a year now and it works really well but we have had to replace it an number of timed due to distortion, hence the use of ABS or PETG.
