I made a mod for the G29 because I was unhappy with the tiny wheel of the original G29. It is fully reversible, wont void your warranty and does not require any wiring or soldering skills.
I also made a very easy magnetic paddle shifter mod because the ones I found on Thingiverse all swapped the original paddles for printed ones and I wanted to use the metal ones. Also no soldering, cables and fully reversible.
You can download the shifter mod for free here https://www.thingiverse.com/thing:3411628
For those who dont have a 3D printer at home, I now sell the printed version of the the wheel and the magnetic paddle shifter mod on Etsy for very reasonable prices (basically just to recoup my filament costs). https://www.etsy.com/uk/shop/MVHStudios
