I'm ready to try a lithophane with PhotoVCarve, but I don't guess it makes much sense if I don't have a way to view it first. So, I put together a set of plans for a display box that you can change lithophanes in really easily, and it makes a nice addition to a mantle or shelf. This is just the first prototype from first iteration plans put together today. Still have some refining to do (like round corner edges of the box tower). Later I'll draw up some really classy looking embelishments. The idea is to be able to change lithos by lifting off the top, pulling the old one out and dropping in a new one.
Also... this one is select pine. The final(s) will be oak. Wanted to play around and prototype on the cheaper stuff. Everything cuts from a single 1" x 8" x 4' board, centered on the table of an AR8. $10 worth of wood ($20 for the oak). I also have a white reflective slide-in mounting board for the LEDs, and a slide in diffuser to help disperse the LED light more evenly against the back of the lithophane. We'll see how that does after I get the LEDs added.
Needs brad holes filled, sanded and finished. I just want to be able to view a lithophane for now.

Nice project. There is lots of interest in lithopanes, but they always need back lit for the best detail. Great job! This is a highly versatile design that can be used for so many sizes and layouts.

My first lithophane went great. The roughing pass took 11 minutes, but the finishing pass took right about 8 hours. As recommended, I roughed with a 1/8" tapered ball nose (TBN), then finished with a 1/32" TBN. So fine a line you couldn't see it moving when the line advanced. But, the photographic detail reproduced is incredible. I added the LEDs and wired in an adapter port and on/off switch. The switch panel was supposed to be at the base, but when you don't pay attention to details, it ends up elsewhere. The next switch and power port holes will be incorporated in the layout and cut during the original production, so as not to have a screwed on panel. Ended up placing the LEDs in the outer perimeter of the interior due to the hot spots of the LEDs being visible when the lithophane was view with LEDs directly behind it. This eliminated the need/use of a diffuser panel. The white reflector backboard is still a good element to evenly diffuse the viewing light. Honestly can't believe the detail in the backlit image. The image here doesn't do the real thing justice. The iPhone camera stopped down for the bright intensity, and washed out some of the image. The lit lithophane is an amazingly good grayscale representation of the original. |

I recently found out about this site for lithopanes and will be giving them a try very soon. candlestonegifts.com/ |

Could you share the file for the actual boxs. What to try these lithographs. Thanks!
