I want to make this fish-box. I saw it on instructables, http://www.instructables.com/id/Generating-elliptical-boxes-using-a-laser-cutter-a/?ALLSTEPS.
I had planned to use a wood dye to color the boxes once I assemble them. I have a wood stain kit, https://www.amazon.com/Wood-Dye-Aniline-Color-Powder/dp/B00BAKWTMQ/ref=sr_1_1?ie=UTF8&qid=1490464519&sr=8-1&keywords=wood+dye+stain+powder.
I am planning on using my small spray gun to apply the stain so that I can control the color and density of the stain. I got my paint gun from Harbor Freight, http://www.harborfreight.com/touch-up-air-spray-gun-66871.html. They are real cheap, but work pretty well.
If anyone has made this box, please post it because I would love to see it. Here is the file to make it.
