Bosch MUM shredder bushing

Kitchen robot Bosch MUM/MUZ/ProfiMixx have a shredder attachment. This consists of several parts including a central bushing. The original part is made of nylon for low friction sliding. But this part can be lost especially in 4 series (44, 45, … 48). In 5 series (MUM5, MUZ5, …) they have added pads to secure it.

This printed part is made for 4 and 5 series. It is much longer than the original to press fit into the center. It's much harder to lose it during cleaning.

Use some low friction material that can withstand washing e.g. PET or PETG. Nylon is the best but much more expensive.

Use random seems to avoid gaps or blobs on single place. It can be printed in vase mode if you set 12 mm (60 layers @ 0.2 mm/layer) as bottom solid layers.
