This Quick Release for the Thrustmaster T300 is for those who want to have a proper QR on the T300. It is based on the QR2 from Fanatec (not compatible) but adapts T300 with Ferrari Alcantara steering wheel. If you have a different steering wheel check the compatibility or edit in CAD. You will need two 5x5,5mm axles, four 6x45mm springs and 6 M3x20 countersunk bolts and 6 M5x15 countersunk with corresponding nuts and 3 M4 threaded inserts. I recommend a print density of 70-80% for additional reinforcement there are holes for metal rods.
