I designed this to fit the default 90mm heart lithophane off of the lithophanemaker website.
I printed it face down with supports. Note that there is only one small support required for the bottom of the heart.
The Standard size frame is 9 1/2", so it needs a "Plus" size printer to fit.
The "Small" stl is for more standard printers like the Ender 3.
