M8 bolt bracket

At work, I need to use various types of M8 bolts, with specific lengths ranging from 10mm to 100mm. There are so many specifications that it becomes very troublesome to track which ones are running low, which ones are still well-stocked, and to sort, organize, and find them. Therefore, I created this 3D model and am sharing it with everyone here. This model has the following advantages:

1. Large capacity: It can hold up to 81 bolts at maximum.
2. Small compartment at the bottom: Designed for storing nuts.
3. Easy measurement and observation: Allows for convenient checking of bolt lengths inside.
4. Efficient organization: Bolts of typical lengths can be placed in individual slots, making them easy to sort and tidy up.
5. Two-part assembly: The model consists of two parts and can be printed without requiring any supports. You can assemble them using M2 screws or simply glue them together.
