TwoUp Bowden J-head Mount

I finally gave up on my AnUbis and got a J-Head. This is a simple (mostly) screwless J-head groovemount. it has two screw holes for a fan to cool the PEEK barrel. It fits almost perfectly glued (or screwed) to the back of the bearing holder here (https://thingiverse-production.s3.amazonaws.com/assets/2b/8d/06/b3/f8/YZ_carrier.STL) i used some double sided foam mounting tape. Let me know what you think in the comments. I LOVE feedback.
