90 Degree pipe for Hecht Solar collector

I have for my swimming pool the heater from the company “Hecht”.

For my requirement, I needed a 90° pipe in order to fit and lay the hose properly.

I've made three hose diameters with a strong support, so the hose clip can be tighten well.

The Diameters are: 

39,6mm

36,0mm

31,0mm

If the smaller diameters are not required, they can be easly cut off.

In my printprofil, there's a pause befor the first 45° pipe, in order to place the original screw cap on the print.
