Description
I had uploaded a feedthrough for the MMU previously, which consisted of two parts.

Since I was upgrading to the MMU3 I decided to take another look at this part. I decided to make it one piece and opted for an elliptical design.
It can be tricky to print as there are some overhangs and bridges. So make sure you have good cooling. It can be printed without supports, but I found using an organic support helped a lot with the aesthetics.
I also tried to print it multi-material using the no-sparse-layers wipe tower but ran into some issues if the filament failed to load. It went into crash detection and kept ramming into the print. Apparently, if you disable crash detection it will work. But I didn't want to risk it again as it failed close to the end.
Crash detection is found in the settings section on the actual printer.
Just wanted to add this incase anyone else tries this.
Things needed to be done prior to installation:
You will need to do the Hinge lid upgrade:

You will need to purchase the tube connectors: https://www.amazon.com/gp/product/B01IB81IHG/ref=oh\_aui\_detailpage\_o00\_s00?ie=UTF8&psc=1&tag=tv-auto-20
