Universal Car Tablet Holder - 1" Ball Arm Mount

This is a remix of the excellent Universal Modular Car Headrest Tablet Holder by Clayton Merkle. 

Universal Modular Car Headrest Tablet Holder by Clayton Merkle - MakerWorld.

 

I have modified the model and added parts so it is compatible with the RAM Mount Arms for 1" B Ball (25mm). 

This way you can have the tablet floating in other positions instead of at the center of the headrest mount. This is useful for people sitting in the middle seat or if 2 people want to watch together. 

Like the original model, 4 M3x8 screws are required for assembly.

 

Some other improvements I've made to the original model are: 

• An end cap for the holder
• Some modifications to the holder itself so it can be printed on its back and have a nicer surface finish and higher quality thread.

For strength, print in PETG and be generous with wall loops, especially on the ball joints. I've tried multiple print orientations for them and the best balance between strength and print quality ended up being printed at a 15-20° inclination. (As it is in the print profile)

 

If grip on the ball joints is an issue, I've found that putting some PTFE teflon or electrical tape around it helps.
