Subaru Center Dash Cubby Mounting Bracket

I was looking for a 17mm ball mounting bracket for a phone holder or tablet on my old 2005 Subaru Outback. I found a couple on ebay, but didnt feel like spending $40+. This should fit the center dash cubby in any 2003-2009 Subaru Outback/Legacy, it will be snug and you will not be able to close the door. But the intent is This is one of my first models made in TinkerCAD, I would appreciate some constructive criticism.This is my first iteration, and will try to make another at a later point (eventually) Also I'm not sure if I'm providing the deserved credit properly, because I needed a 17mm ball mount, Rather than making the ball mount from scratch, I just grabbed his. Please let me know if its an issue, and I will create mine from scratch @Tylercowen and his 17mm ball mount for windshield etc.https://makerworld.com/en/models/245275-17mm-ball-mount-for-windshield-etc?from=search#profileId-261669
