"nearly friction-free pad" vs. really good bearings?
I have my doubts.
Seems like a bad idea to me.
What is the point?
Why would/should "tonearm wobble" bother anyone to start with?

I never had a real problem with wobble until I tried the 3D printed arm and then the wobble was obvious while the cartridge was tracking off center and / or warped records. When I went back to my older version JMW-10, I had no issue with wobbling and I think it's because of the fluid damping. It's a shame the latest arms offer no such option.
Waxxy....what cartridge are you using....and are you very sure all your setup adjustments are good? My 3D is rock stable....the arm is internally damped...no need for external damping.
I used a Koetsu, 47 Labs, and Dyna Karat. Aligned using either VPI's jig or a Dr. Feickert alignment tool.
BTW, the internal damping of the tonearm material and fluid damping of the motion of the arm are two separate things completely. The arm material and internal damping is to control the resonance of the arm itself, while fluid damping is used to control the motion of the arm / cartridge combination.
I wasn't aware of that fact.
Maybe a mod to include fluid damping would be more fitting?

"Why would/should "tonearm wobble" bother anyone to start with?"
I never understood posts mentioning how the unipovot arm is unstable WHILE just holding the tonearm.
Using the cue lever to lower/raise the arm, there isn't an issue once the needle is in the groove.
If this was a free mod, I would send my arm back just to try it. Otherwise, I will await posts of owners doing this mod. I have a 1K cart on my Classic, it sounds fantastic.If it will make it sound like a 10K cart, i'm all in!
"Using the cue lever to lower/raise the arm, there isn't an issue once the needle is in the groove."
And once "the needle is in the groove" is all that should matter.
Adding more friction to the system to solve a non-problem just doesn't seem right to me.
