I took the amazing Lantern design made by Laptop-Guy and made a few fixes he did for future lanterns.  My biggest issue with the original was due to how it was assembled one side would end up thicker than the other so I added a 45 to the panels so they fit together better and have an even overall look and adjusting the size to match later lantern designs.  In doing this I also had to adjust the base to fit the new dimensions.  Finally I made a custom decorative lantern cap for a bit more style. If you don't like the decorative cap print the base twice, or don't use a top, the choice is yours.  For joining the panels I recommend double sided tape but you could use glue if you like.  For the light inside I have a votive led light or you could use a small led battery operated candle as well.  I printed mine in a black pla.

Printing Instructions:

I printed the panels with a .4 nozzle at a .2 layer height with 100% infill.

The base and top I printed with a .4 nozzle at a .2 layer height with 20% infill.  The decorative lantern top will require supports.
