You need Bearing 6803 2RS 17x26x5mm

(https://www.amazon.pl/s?k=17x26x5mm&__mk_pl_PL=%C3%85M%C3%85%C5%BD%C3%95%C3%91&crid=18ZH5BA2BUPJ7&sprefix= 17x26x5mm%2Caps%2C108&ref=nb_sb_noss_1). 

It is best to print in one color. I prepared it in two colors.

It is best to press the bearing when the filament is warm. (watch out for burns)
