Eheim aqua ball - holder no suction cup / Halter ohne Saugnäpfe

My aquarium filter held with suction cups always slipped downwward.
Therefore I designed this holder do fix the filter.
I furthermore added a support at the bottom to keep the filter in upright position.
If you need some other extends I might prepare the hook as customizer.
Added some different lengths as I recognized length 100 would be better than the original one with length 90.
