Pool enclosure

This are enclosures for pool hoses (30mm) to fit in a 70mm KG tube (small / klein) or 2 in a 100mm diameter tube. I used it in the garden to connect the pool with the pool filter. for this I have buried outlet pipes in which I install the hoses. So they are protectet. To fit the inlet I have created this houses. now they are in use for about 3 years without problems.

I printed it upside down, so I Need no support
