Hmmm … Is this Patrick or “Jackie Ho”? 
Regardless, glad to hear it’s working for you!
I am tending to shy away from sharp cutting tools when wearing gloves and working with slippery resin … but I imagine the exacto knife is a good tool to have around, to start the process of removal, particularly if it’s a stubbornly adhered print … even with the notches in the support foundation. Good tip also.
