Ergonomic Lint Roller Handle

About  

I bought lint roller refill on Amazon, and had the surprise that the internal diameter was slightly to small to fit with the Scotch Brite handle I had.

Here is a simple proposal, one part only.

The Freecad model is also provided.

Printing

Printed in PLA with 15% filling, PLA.

Nothing special in the settings, except that it has to be printed without support, but with brim.

Be cautious when removing the brim, the part is fragile. I recommend to first remove the external brim, then cut the notches without removing the internal brim, then remove the internal brim.
