About this part

# Toyota GR Yaris rear diff cooling duct
3D printable rear diff duct for GR Yaris.

## Technologies
- FreeCad

## Printing
Part in split into separate bodies, but large printer is required for main bit. Idealy something around 35x35 (like Qidi X-MAX3).

Main body can be split in slicer into two halves to avoid filament waste on supports. There is a lip on the edge which allows to either plastic-weld it with soldering iron or to glue it together.

Other pieces are a press/snap fit, but glue is recommended to keep it all in one big piece.

### Parts:
- Inlet - cutout holes for main body are already bigger, to account for printer tolerances (as scaling this part in slicer would be hard)
- RearHanger - probably safest to scale it to 102-103 %
- Outlet - probably safest to scale it to 99%
- MainBody - print "as is"

**Bear in mind that due to printer's tolerance - You might need to scale some parts up/down.**
