'FlexiArm Arc'-side brush adapter for Roborock

This adapter allows you to use the anti-tangle ‘FlexiArm Arc’-side brushes from the newer Roborock models such as ‘Qrevo Curv’ on all older Roborock models with the hexagon-shaped axles.

I've been using this adapter on my trusty old S7 MaxV and my Qrevo MaxV without issues.

What you'll need:

• one M3x14 screw (flathead would be preferable so I won't stick out and scratch your floor)
• ‘FlexiArm Arc’-side brush (available for example at amazon: amazon.de; amazon.com)

This was printed in PETG at 0.2mm layer height. No need for supports, there is a sacrificial layer that you can punch through when installing the screw.
