Finally, a box that fits your tools, not the other way around. Most parametric boxes ask you for the total size and divide it blindly. This Precision Generator works differently: you tell it exactly how wide and deep each compartment needs to be (in millimeters), and the script automatically calculates the outer box dimensions to fit perfectly. Whether you need a 150mm slot for calipers and a 30mm slot for screws, this model generates it instantly.

Hi! This is my idea for a BMW M3 F80 keychain, created using MakerWorld’s Image to Keychain tool with a few small improvements. I recommend printing it with a 0.2 mm nozzle for the best detail. I hope you like the model!
