Sliding Litho Frame for standard Lithophane Remix

The very first original model did not work as I hoped with the clamps, the remix that was used to make this remix made use of other inserts (slightly bigger diameter). Changes:Holes in the frame are now somewhat smaller, so my M3*L6*D4 now fits (this was too loose before).The base itself has the opening for the USB connection made larger so the cheaper AliExpres Lithopane frome now fits.(with the remix model this was too tight, leading to light leakage).Please be aware of the maximum thickness of the litho, this should be left to the standard 2.7mm (mine are usually 2.5mm thick).The dimensions of the final litho should be: 108 x 144 x 2 to 2.7mm.Many thanks to the orignal creator and previous remixer!
