Car wheel hub cleaning tool

I wanted to have a tool to clean the wheel hubs of my car when changing tyres. 

You can buy these grinding tools, but they were too expensive for me. So I designed my own grinding disc and bought only the attachments and some other parts cheaply from Amazon.

The following parts are needed:

• 1x screw M8x55
• 1x disc M8x25
• 1x nut M8 (self-locking nut)
• velcro tape from Amazon → 8,5€
• sanding attachments from Amazon → 28,5€

I have uploaded 2 versions of the grinding disc
Version 1 -> standard
Version 2-> 20mm smaller (saves time and filament)

Printing

• 0.6 nozzle
• PLA+
• 40% - 45% infill
• 4 wall lines!
