Bathoom floor drain
This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/jXXVBjtoScm
I needed this in my bathoom for inserting a pipe diam=40mm in center hole in bathoom floor drain.
Printed in PET-g for about 2 hours on Ender 3 Pro with the 0.8 nozzle, bed 75, nozzle temp 235.
This is the quick and dirty print, but it surves its purpose.
