Announcing ETT adapters for Meta Quest Pro!

Quest Pro controller is a brave new step by Meta. It can be used with either Quest Pro headset, or Quest 2 headset (which I am using).

This controller uses its own 3 cameras to track itself. So the user doesn’t need to worry about controller leaving the headset camera view again. In ETT terms, this means the player can perform a very large&sustained back-swing for that juicy forehand loop. They can also do behind-the-back shots with ease.

Benefit comes with cost too, the Quest Pro controller itself is around 160g, so with the adapter, the whole racket is around 210g, which is still within the range of real TT paddle weights, especially for loopers. 

For me, the weight actually was quite easy to get used to. The racket still has a realistic center of weight, so with the somewhat proper technique, I didn’t get any injury or discomfort after the 2 weeks ongoing testing. In fact, I am in love with this controller right now, because the added weight helps stabilize the racket angle, and I feel its tracking is actually slightly better than the Quest 2 controllers.

I’ll keep using the Quest Pro controllers with my Quest 2 headset and see if it will help me to break the 2700 ELO threshold.

SolidSlime Quest 2 adapter changelog: 2.1


  • Thumb screws are used to secure the two pieces of the adapter. So there’s no need of screw drivers anymore! The weight has increased by 2-3 grams, but I think the convenience is worth it.
  • Changed main color from dark grey to light grey. This color matches the Quest 2 controller quite well.
  • Handles are now printed with Wood PLA to make it both look better visually and more comfortable to hold. Smells nice too! (Since there are difficulties in sourcing and printing in Wood PLA, I’m not sure how long I’ll keep doing this. )

You can find the latest version of SolidSlime Quest 2 adapter here:

SolidSlime Quest 2 adapter changelog: 1.9, 2.0

SollidSlime v2.0

Hi all,

I’m happy to announce some changes introduced in the recent versions of SolidSlime Quest 2 adapter, in version v1.9 and v2.0.

As always, the version can be found at the bottom of the handle.
Below you can find the latest paddle position code for all my adapters. In the next update of Eleven Table Tennis, they will officially be included as presets that can be chosen from a list.

Before going into the details, I’d like to express my gratitude to the players who gave me valuable suggestions and feedback. These improvement won’t happen without you. Thank you!


v1.9 is a big list of quality of life improvement.
I ticked as many boxes as I could from the todo list, before moving on to v2.0.
All v1.X versions share the same paddle position code 4008.25. (This one is more accurate than the old 4008.17)

  • Changed the shape of the blade so people with bigger hands have more space to press their index finger (thanks JensME).
  • Rounded the corners in many places to make the hand feel more comfortable, especially for people that have a deep grip (thanks PPTim and others).
  • Now the index finger will not press on the line where the two parts meet again (thanks kwak).
  • There are some flat surfaces on the top of the adapter, which can be used to glue/tape lead tapes etc. if you would like the racket to be more head heavy. (Please make sure the weights are secured!) (Thanks PPTim)
  • Changed the shape of some critical parts to make it muuuuuch easier to insert the controller into the correct location, without hampering the solidness of the racket.
  • Changed screw locations so both screws are entirely hidden from view now.


  • Changed adapter orientation in order to give more room to the tip of the thumb finger. Theoretically this has the benefit of improving the FH tracking further more too, because the right side of the ring (in the picture below) will be more visible to the camera during a FH stroke. (Thanks Sulik)
    Since the controller position has changed, there is a new paddle position cloud code for v2.0: 4008.26

v2.0! Woohoo!
