A tool holder that can be printed in one piece with different sizes of sleeves from 2mm to 17mm.

I have designed some concentric circle sleeves, you can choose the right size to place your tools such as screwdriver, hobby knife, etc. according to your needs.

It has a rotating lid at the bottom so that neither the sleeve nor the tools fall out. Also the hexagonal shape plus the snap structure can be combined freely. You can print in a variety of colours to distinguish different tools.

If you intend to print your own using the STL file, the default position prints out with the sleeves attached and you will need to cut them apart. If you want the sleeves to be separate, the main body needs to be sunk 0.2mm, You can just change the positional height of the model to 14.9 mm.
