A simple block to keep the bits that came with my cheap rechargable rotary tool organised and easier to access.
Put in a colour change at 21.20 layer to print the drill bit size numbers in a different colour.
The hole tolerances were made with Prusa printers in mind. Depending on the accuracy of your printer, you may need to drill out some of the holes, but then, you obivously have a tool for doing that.
The author marked this model as their own original creation.
