UPDATE: I have scaled to 101% as I was occasionally having issues with fit. I have also made the legs 100% infill for strength after dropping 2 and deeply regretting it

A lithophane cube lamp which fits MakerLab generated lithophanes sized 100x100mm for the image (104x104mm total including border).

I tried a few of the available options and I wasn't happy with the fit so I designed this one to overcome the issues I found on other models.

Instead of sliding between rails, the lithophanes are slotted in top and bottom and supported on the sides. There is extra space in the top slot to allow a flush fit instead of the gap I got in others. The central pillar is the same height as the corners so that you can put a spot of CA glue on it to hold everything together if you so choose (photo is of an earlier revision before I made this change).

The cable slot is a snug fit side to side for 3mm cables but has an extra 1mm depth so that the base doesn't wobble. I recommend a 1m LED strip to fit the height of the central pillar.

Can be printed in two parts on the A1 mini
