Play doh plastiline roller with bearings

Roller to crush and play with plasticine, thanks to the bearings is easier to use for children.
You need two bearings 608 2rs 8x22x7mm.
The filling of the shaft is 100% and the roller and handles at 40% PETG and hot bed 85º
I want to improve the design to avoid supports inside the handle, it depends if you like it.
Thank you!!!
