I made a model to add to Simplify3D which visualize the printbed and the bracket from the E3D Tool Changer.
It has no function, but looks nice.
If you want to add the model, just got to Tools -> Options -> Machine -> Printer Models and add the .stl and choose your color.
If you have problems with disappearing model, look here: https://forum.simplify3d.com/viewtopic.php?t=3758
The author marked this model as their own original creation. Imported from Thingiverse.
