We're back to keychains!! This is the absolute final push. I am determined to get these out in shops this time!! I designed the 3d printed cages for these in mind with the exact printing specs that I had in mind. A layer height of .25mm in mind. The bottom and top of the cage is 1mm thick. The 4 layers on the top and bottom give enough room to power sand the 3d printed cages down smooth, and the 1.75mm hollow part gives enough room to shimmy the 1.5mm thick piece of engraved wood inside of the cage in the middle of the print! 

The hardest part about these is creating the pattern in the 3d print. It leverages booleans using a cutting place to create a high(relatively) resolution cut through the 3d base mesh. This is a heavy computational process that likes to freeze blender if you push it past it's limit. Each click on the computer causes blender to freeze for about 20 seconds or more when creating these. After 7 iterations and some frustrations, I have a nice pipeline to make more of these! Hope to really get creative with these things!!
