Roomba replacement roller Aggression 20

I use a roomba 890 and these rollers work great. Printed using Siraya Tech Flex TPU Filament - 85A https://www.amazon.com/gp/product/B0CP1YS9N6?th=1 I used the customizer and lowered the aggression down to 20 from the default 40 to reduce noise and hard floor hop. On carpet it sounds about the same as stock but tile floor its still loud. Maybe next time ill reduce aggression down to 15 but if you have carpet this is perfect. I did go with tpu 85 vs 95, creator used 95 but I personally thought that was too hard a filament for this. Notes on using TPU: DRY DRY DRY and use a low friction spool adapter so you dont under extrude. When dissasembling old roller, cut the old rubber off, your'e not going to be able pull it off like you can slide these on.
