CTC Formaker end z axis modification/upgrade

I added a microperforated plate for better hanging of the ABS, having had the laziness to do a recalibration plateau I thought to make a hold of the thickness of my plate like that no need to recalibrate all my tray.
You can modify the thickness of the wedge by importing the STL into tinkercad and provide yourself the thickness of your tray that you will add in order not to have to make a total recalibration of the plate.
