Thread: Adapter for DC 6" to twin 4"

Just a little nudge

SirNed, PM me your phone number and we can organise how to send it.

Chris's solution wil undoubtedly be 1000% simpler but FWIW If you have a largish 3D printer, Thingiverse.com now has a file that allows you to print one for yourself.

file is called 6x4x4_SD_Wye_fitting.stl
The foot print is ~170 x 265 x 302mm plus any brim surround which is advisable on such tall print.
It would be interesting to see how it would print the 4" arm hanging out into space.
I set the support for >45º which means it will only print support for that the small red section under the outer angle collar of that arm

For my printer, print time under standard printing conditions is estimated at over 2 days and even then it might not fit first time and adjustments need to be made and reprinted.
The reason I have not made one is that it consumes about half a kg of filament, This would be about $10 worth of budget filament, or $20 for more expensive filament.
Compare this with a standard Stormwater Wye plus a standard DWV level invert that would cost around $26 and it's borderline worth it
The 3D printed design would provide a more efficient sir flow (level inverts are not very efficient) so that would be something to consider.

Its still early days for 3D printers but it shows what is currently possible.

Hi Bob,

How would the 3D printed fitting compare to a standard fitting for wear and tear/stress? I suppose they aren't under a lot of stress, so probably not a big issue?

I have two Clearvue items, one with internal blast gate and one without, neither have ever been installed.

Correct. It also depends what plastic it’s printed out of but I’m find even the weakest plastic (PLA) is fine for 4” stuff. If you needed a tougher material there’s always PETG (like PET) although is a bit more expensive. If your printer can print it there’s also polycarbonate but again more expensive 😀
Another possibility is to print a bit thicker
