Customizable Bit Tray

thingiverse

Updates: 2019-01-06: Fixed OpenSCAD file; now working with Thingiverse Customizer (removed non-standard characters). Corrected some typos. This space-efficient, customizable holder for tool bits such as those used by Proxxon or Dremel multitools is designed to maximize storage density. The holes are arranged in a hexagonal pattern, allowing for up to three different hole types with individual diameter and insertion depth to be defined. This enables the combined storage of different shaft diameters, as well as the possibility to place less frequently used tools at a lower plane, hence larger tools like cutting wheels can be 'stacked' on top of each other (see photos). Two of the three hole types ('type 1' and 'type 2') can be indicated by marker pits, making it easy to recognize different depths prior to bit insertion without trial-and-error. For some reason my OpenSCAD designs tend not to work reliably with Makerbot's customizer on Thingiverse, so I recommend using OpenSCAD's built-in customizer. It has the advantage of allowing parameter sets to be easily stored in a '.json' file and later recalled on demand. A few configurations are included in the provided .json file, as well as .stl files. Instructions: Simply copy the .scad and .json files into the same folder, open the .scad file, and launch the customizer by checking 'Edit -> Preferences -> Features -> customizer' (you may need to scroll down), then uncheck 'View -> Hide Customizer'. Note that at least a 2018.x version of OpenSCAD is required: on the download page (http://www.openscad.org/downloads.html) scroll down to 'Development Snapshots' and download the newest version. Printing is straightforward; no support needed, with an infill of 10% sufficient.
