About this 3D model

I thought to myself what can i do with a used can? Well it is actually a old idea i had for some time, but with the contest it just al came together. What about a refillable paint roller. So print the parts, cut off the head of the can. glue the parts together and fill the can and paint away. Good luck printing Printing the part is best done with 3 parameters. And a 50% infill. Not on the handle, but on the head part.
