CR-10s simple filament roller adaptor - Arianeplast

I use Prusa filament for printing on my CR10s and the roll is hollow at the center with an inner diameter of 55mm. So, solutions based on ball bearings (like https://www.thingiverse.com/thing:2186682) do not work. Also, the thinness of the ball bearings makes the roller unstable and 625 / 608 ball bearing models are too high to have standard support + adapter entering into the roller hole. So, I decided to design my own model in order to improve a bit the standard CR10s support. To make printing easier without support, I separated the piece into two parts (to be glued together before mounting on the support). This avoids having to manage supports for the groove. You need to print four adapters for a single roller (two grooves + two sides). If you have a 1kg and 750kg filament rollers, you can print a third adapter (one groove and one side more) and place it between the two supports for standard 1kg roller. Feel free to test and comment.
