This is a remix of Bath Drain Strainer by SoberCannibal. The outside diameter of the strainer portion was downsized to 35mm, which puts the top ring's diameter to around 64.5mm. The original didn't fit in my shower's drain. I've also made the top ring solid for more rigidity.
I'd recommend a higher temp filament such as PETG or ABS over PLA due to higher water temps.
