If using white filament for the Diffuser Screen, printing it on a textured plate will make it scatter more light and be dimmer. Use a smooth plate for best results. A textured plate will work great for clear filament though :)

easy print, turned out awesome. I found a tablet stand on here and modified it to work with this frame and it is perfect. I also removed the printed diffuser and just used actual diffusing sheets which were perfect and allow for very good light transmission. I'm sure the 3D printed one works fine too but I have these on hand already.
