# Vacuum cleaner

My neighbours gave me this vacuum-cleaner brush that didn't work anymore because it stopped spinning. The connecting piece was so worn out, that the "clutch" piece would spin freely inside it.

I 3D-scanned the clutch with our CR-Scan Raptor in blue laser mode. For this to work, you need several tracking points around the object.

Here you can see the result of the scan.

I used blender to postprocess the data into a positive part and a negative copy that fits into the center of the brush.

In order to make it removable, I drilled a hole through my printed piece and the brush, in place of one of the screw holes. Now I can securely fix the part in rotation, but still dissasemble and replace it if neccesary.

This is what the finished result looks like:
