I made this 4 sided candle box without tabs. Instead I cut a small band to go around around the top and bottom to hold it togather. The pictures shown are before it will be glued.I made mine  5.5" with 2 sides(5,5 inches 6mm (the width of the wood, so you have a square box).  Just ask if you have questions. I'll try to log in on my pc and add the lightburn file.
