Hello everyone,
I just wanted to present my T300RS wheel modification I just finished, if it can help someone or just give ideas for your own project.
I used a GT2i 34cm wheel: ( https://www.amazon.fr/gp/product/B00TFAICUG/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 ), some switches ( https://www.amazon.fr/gp/product/B074XDQL7Y/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 ),
made some parts with Tinkercad then "3dprinted" them (switches supports, paddles fixations, wheel adapter) and also used some threaded rod with lock nuts. None of the original parts were altered or modified excepted solders I made on the board. No keys were lost: I kept SE an ST original keys, but linked all missing ones to my new switches. Yellow: 3 and 4, Red: 5 and 6. Blue: L2 R2. Center: up down left right and the most important !!!!! the Green for the horn !!!! (PS key ). Paddles are still on 1 and 2.
