Unanswered E3D-6 Assembly Issue

Hey there!
Hope someone can help me! I was setting up the E3D-6 print head for my Robo3D. One of the steps was to drill out the hole a little bit so that the printhead could rest correctly on the carriage, as well as to provide enough space for the feeder tube to go into the print head. Unfortunately, I accidentally drilled a little too much, and the feeder tube is a little loose when put in. Any suggestions as to how to handle?

Thanks!
Steve

 

Don't worry about it. It'll be fine
