Heavy Duty Fanatec QR1 insert

The Inventor model has 2 parameters “Wanddicke”= wall thickness and “Bodendicke”= bottom thickness. Change them to your needs. Keep in mind, to change the layer height accordingly. 

The provided stl files have a wall thickness of .6mm and the bottom thickness is .2 or .32mm. If you don't have Inventor, but want to use a different parameter just write a comment and i can generate the new stl file for you.
