Core One modified "bowden-bend" with wider radius

• Especially when in use with the MMU3 community edition, there is more space to the top. A wider radius on the bowden bend leads to a smoother loading procedure, what enhances reliabilty of material changes
• Additionally I found it helps a bit with flexible materials, as there is less friction in retraction moves.
• the inner channel is a bit wider than in the original, so it's easier to move it around, if you have to do maintenance and might need to remove the PTFE tube from the extruder pushfit. The original was in my case very tight in that regard.

I printed it in PETG, works fine.
