Thinner diffuser for lithophane frame

My model fixes 2 issues with the original diffuser for bambu lithophane frame - making lithophanes too dark and rattling in the frame. My design has a relatively thick frame for strength and a thin “window” in the middle to let more light through while still diffusing the light. It's also 0.5mm wider to help with the rattling. It's available in 6 thicknesses: 0.2mm, 0.4mm, 0.6mm, 0.8mm, 1.0mm and 1.4mm (as thick as the original diffuser). I recommend starting with the 0.4mm or 0.6mm diffuser and checking if you like the results it provides. Boost MeI'm raising money for filament to be able to develop more functional prints for you. Every boost is appreciated. Thank you in advance :)
