This is a Printable Decorative Triple Incense Burner with a removable collector box, so when you have to empty the ashes, you just have to extract the box as a drawer, clean it with water , and put it on ! Burn 3 Incense Bars at same time to get an extra flavour to your home :) (you can only use 1 bar if desired!) The Triple Incense Burner got a container to hold all you incense bars for future use. Very stylished and functional in my opinion. Designed on Sketchup, the Source file is published, so you can improve this design! I printed it with 0.3 mm and PLA. Use 3 mm of brim for avoid warping. If the holes are not clean on the end of printing, warm a wire and put it on the holes to clean them. The box is with the exact fitting size, i recommend you to scale the box at 99.5% so it will fit in without having to brush the holder. Enjoy!
