This kettle used to have a lid optimized for coffee, used to have an inbuilt filter which made it useless for tea. I 3D printed a new lid that is optimized for tea. I have shared a photo like this, but in this photo, both model and material are upgraded.

 

As information, I designed it using @SolidWorks. I 3d printed it using @makerbot. I used @proto_pasta ‘s High Temp PLA 2.0 to print.
