Industrial pipe components for Warhammer40k

Component list:
-90° elbow LEFT hand turn
-90° elbow RIGHT hand turn
-90° elbow DOWN/UP turn
-Little top T-section cap

I have made 3 different elbows, and a top cap component that can be added to a length of plastic piping.

The specific pipe I used is shown in the link below, but you can try other pipes as well as long as the outer diameter is 42.27mm or 1-11/16th".

I have included a link below that shows the type of pipe you should use for the straight section:

I used a "Form2" printer, @ 0.025mm print resolution to make the parts shown in the image above, so you may need to do a bit of sanding and finishing if you plan on printing with any printer that works at a lower resolution.
