This is a highly customizable frame for hanging flat 3d prints of any nature but specifically for lithopanes. many times people want to hang their lithopanes they just printed off to allow light to shine through however due to there being no way to hold the print they simply tape it to a lamp shade so my design makes this much simpler by having a hanger so as to allow a string such as nearly-invisible fishing line to hold your lithopane in a much simpler and more elegant manner than before.
