5. Print 8 lithophanes, 80x80x3mm and make sure you use 2mm frame so it fits perfect in the designed slots.

Assembling the components together:

Place the lithophanes in the desired frame. The lithophanes should be sticking upward 2mm, creating a slot for the frame top to be snapped in place. (Note: the frame has a tolerance of 0.4mm for the thickness of the lithophanes and 0.4mm for the length). You can use a drop of superglue on the frame top to secure it to the lithophane frame if you wish, but there is no need.Wrap your LED strip around the cylinder and make the required electrical connections.Assemble the frames and place them on top of the lithophane base.Using a M3x12 screw, secure the lithophane top with the cylinder from the lithophane base.Light it up and enjoy.

Printing this model is straight forward. Use minimum supports at the base (for the LED wires), and at the slots for the spinning mechanism (for the frames) and the lithophane slots for the frame top.

Print your lithophanes at 0.12 layer height.

Be careful if your bed is not leveled and you have elephants foot. If your printed parts are not fitting together, use a razor blade to carefully trim the edges of the notches. It has 0,4mm tolerance for that purpose, it should be perfect for you too.
