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

thingiverse

The is a T joint designed in Fusion 360. It is a good fit for 3/4 or 21.5mm waste pipe available in the UK. The 21.5 waste pipe from B&Q to be precise. I believe that there are other sizes which might be sold under the title 3/4, so being specific that available from B&Q and sold as 21.5. In Homebase it is 22mm and I have no idea if the joint will fit but of course it can be scaled if you are prepared for a bit of trial and error. It will join the pipe so it can be used for framing for photography backgrounds or other structures such as 3D printer enclosures. This was printed in .4 rough draft and I am unsure if the quality of the print and tolerances that your printer may print to will effect the diameter. You are of course free to scale the item if you feel that it will be a more optimal fit at a different size. You may also scale it to use in a different application. I initially printed these upright (Doh!`) if that is the correct way to describe it but I suggest that it would be better printed flat with the cylinders all against the print surface. As you can see I had another go flat. Naturally the result was much better. The fit is much better. In Cura, if a brim is used not a raft, some of the brim will be difficult to remove, so leave that on. This makes for a tighter fit. It is a good tight push fit which will hold the tubes tightly. I have printed on glass therefore if you use another surface the fit might vary. Check what your slicer says about time and materials consumed but I believe that the solid shape may print more economically than if there was a void. If you print this please add a photo. It will be interesting to see how other people have printed this and what wacky colours you have used.
