I have a suspicion that a Chewbacca is using my bathtub, so to avoid hair clogs it was necessary to utilize advanced 3d modeling tool and modern fabrication method. Provided model is for 47mm drain diameter, source file ready for modifications is also available.
Version v2 has some improvements: if you want to tinker with FreeCAD you can easly change dimmensions.
P.S.
If you are in need of specific dimmensions drop me a message.
The author marked this model as their own original creation.
