The original design does not hold anything in place, so if the roller falls out when moving, so do the bearings. I increased the diameter of the pegs so that they fit snug (red pic). Take care pressing the bearings onto the roller, as there is a gap made by a spacer and will not seat flush. Pressing at an angle may crack the peg.
If the original was printed and it's loose, you can sandwich a piece of paper towel in between the two parts to accomplish the same fit (grey pic).
Printed in PLA on a Prusa Mini. No special settings (.20 structural, 15% infill), but increasing perimeters to 4-5 won't hurt.
