Magnetic Tool Holder

I created a two holders for the Bosch mini ratchet set with 31 pieces. The first holder is for the bits and the ratchet, and the second holder is for the nuts and the small extention/ adapter for a drill.There is also a small screwdriver thingy, which uses a metal ¼ inch extention as a core. I had it laying around so I used that.There are a total of total of 42 magnets embeded in total.27x 8mm*3mm (8mm diameter, 3mm thick)11x 10mm*4mm (10mm diameter, 4mm thick)4x 10mm*2mm (10mm diameter, 2mm thick) I printed it with 0.15mm layer hight, and I had to print it super slow, since I have cheap and old printer.
