I needed a lantern to display some photos at a memorial so I created this model that will hold four lithophane panels sized at 125mm x 125mm. The entire model is made to be press fit together without any adhesive and the top is only intended to be set in place. The ring at the top was created only for looks and isn't intended to hang the lantern from but if you want to try it, you should think about adding some sort of glue when pressing the ring retainer onto the bottom of the ring and then you'll need to glue the top onto the pillar top. There is a sacrificial layer at the top of  the inside the top piece that you can either just push the base of the ring through or you could use a blade to trim it out.

I printed 6 copies of this with a  6mm nozzle at 2mm layer height and had to do minimal post processing to get the parts to fit. The only part that I used supports on was the ring so if you print the ring on the same plate as the top, be sure to place some support blockers on the underside of the sacrificial layer.
