Hose adapter for pool vacuum cleaner

In order to connect the hose (32 mm inner diameter) of a pool vacuum cleaner to the water outlet fitting (goes to the pump). Tested with Intex pool and pump. The inner thread screws on the outer thread of the pool fitting where normally the grid filter is screwed. For people ho find the tread too tight, I've added poolsaugstutzen_32_plus1mm82.stl where the thread is increased by 1 mm in diameter.
