VW/Skoda/Audi/Seat Fuel Pump Tool

I needed a tool to remove and reinstall the fuel pump of my skoda karoq (diesel). So I designed this. Printed from petg with 70% infill and at least 5 bottom layers, it was strong enough to withstand the remoavl and installation. I tapped the ring carefully using a screwdriwer and a hammer to loosen it a little, then I was able to remove the pump using the tool. 
It is a really tight fit, you will have to press the tool onto the ring.
You can use a wrench with a ½ inch drive.

Thanks!
