Red Sea Reefer Outer Downpipe

This design helps you to create you own Red Sea Reefer Outer Downpipe. I made 2 variants. One adapter version, where you have to place a tube on both ends. Or the full version where you only have to place a tube on the bottom part.

The tube to get for this purpose is PVC 75mm diameter with a inner diameter of 68.5mm.

The top part of the tube including the adapter is exactly 93.5mm for all reefers. So the full print is 93.5mm high. If you choose to print adapter only then cut 90mm of PVC and glue (or make it a tight fix by scaling) it on the adapter.

The size of the bottom part of the tube depends on the Red Sea Reefer aquarium you have. For 170/XL200/250/XL300/350/450/XL425/XL525 this is 34mm.
