heres my idea of poop bin for centauri carbon 2, using the bolt that come from the factory to hang the hook, then slide the basket to the hook. easy mount and dismount to clear out the poop, no magnet and glue needed, just print then attach.

Dimensions for the basket : 160x60x120 mm

Note: you dont need to remove the bottom poop chute screw all the way, just loose it enough for the hook to slide in place then tight it up again.
