Printed Maw and eye so your vacuum looks like Beholder monster. It's made primarily for Roborock S7, but will fit some other Roborock models as well as some vacuums of other brads, especially with scaling.

Printing

Setup filament switch in slicer after each step (0.4 and 0.8mm). Start with red, follow with black and then white. Or choose your own colors.

Attaching

Use PVA glue (washable) or thin double sided tape.

Side effects

Your vacuum will be able to disintegrate obstacles in the way and petrify large pools of liquid, however it shouln't be left running while people or pets are present in the house. For optimal mopping performance, fill the reservoir with blood.
