This is a Quick Release Adapter for the Driving Force GT Wheel from Logitech. It is compatible with the 70mm to Thrustmaster Adapter.

For the Wheelconnector you need 4 M4 Screws. But thats about it. Just print out the parts, remove the wheel from the base and assemble the new parts.

For your 70mm Wheels you can use this adapter (all parts are made around that design): https://www.thingiverse.com/thing:2630578
