The wife came to me and said she wants a box for all of her tips and housings. First I was going to go to my wood shop but said no, the laser can do it. I mad a box within a box. Labeled each one as to what the tip was as well as housing. The inside box needed to be set off the bottom, so I cut 4 pieces of 3mm and glued to inside sides. The inside box was mad a total 1mm skinnier than inside dimension. I used small box hinges and a latch hook for the top. I did use boxes.py (fabulous box generator).
