T joint for 21.5mm or 3/4 waste pipe (UK). Not for plumbing

thingiverse

There is a T joint designed in Fusion 360. It fits well with 3/4 or 21.5mm waste pipe available in the UK, specifically from B&Q as 21.5. Other sizes may be sold under the title 3/4 but being specific about availability from B&Q helps. In Homebase it's 22mm and I'm unsure if it will fit but scaling is an option for trial and error. It joins pipes for framing photography backgrounds or 3D printer enclosures. This was printed in .4 rough draft, with unknown print quality and tolerances affecting the diameter. Scaling is allowed to achieve a more optimal fit at different sizes or applications. I initially printed these upright but suggest printing flat for better results. As seen, a second attempt was made flat with improved fit. In Cura, using a brim not a raft makes some of the brim difficult to remove and leaves it on for a tighter fit. It's a good tight push fit that holds tubes tightly. Printed on glass, the surface may vary; check slicer time and material consumption estimates but solids print more economically than voids. If printed, add photos to see how others have done it and used wacky colours.
