This was designed to fit the towers shown in the photo which I believe is for the B74 and B74.1 The B74.2 tower is wider so I will add a model for the .2 when I can barrow a tower to do the modeling with.
The bleeder screws on the front may need to be facing away from the edges of the guard to clear.
Parts should be printed solid in TPU for best results.
The author marked this model as their own original creation.
