Contest: Gardena 3000/4 Pump Cover(own Compact Design) interior integrated

Since my Gardena Pump Cover exploded in the Winter, and i didn´t want to spent 40-50 Euro for a original spare Part, i thougt it would be a nice project to redesign the Pump Cover, so i can reprint it when needed. And Not throwing away the Pump, making our little blue Ball a better place!
You will need to make sure that it is water tight. The First version I printed was not water tight since i printed it with only 15% infill. I now printed it with 100% infill, which lead to water tightness.I use Petg(because i dont use other stuff)
This Version is my own design, all integrated and optimized for additive construction.
