Gridfinity Customizable Driver Bit Bins

This model is part of the Chunky Tool Wall Collection.  Collect 'em all!

This is a set of Gridfinity bins for ¼" or 6mm hex drive bits.  It has a drive type icon on the side, and It's customizable for the number of bits.  It is specifically designed for my Chunky Gridfinity Baseplates for SKÅDIS, but it's fully Gridfinity compatible.  I've included STL and 3mf files for the 11 bins I use, but the Fusion 360 CAD file is parameterized, and you can create many other sizes.

The icons are

• Hex
• Security Hex
• Hex Socket
• Phillips
• Pozidriv
• Slotted
• Split Slotted
• Square (Robertson)
• Torx
• Security Torx
• (no icon)

The bins have magnet and screw holes on the bottom, and they're stackable with other Gridfinity units when empty.

How to Customize

I've included a .3mf file of the exact set of bins I use, just in case you're my identical twin.  I've also included .STL files of the same bins.  But you'll probably want to customize the model for the driver bits you have.  There are two things to customize.   You do it in Fusion 360.

You can set the number of rows of bits, up to 3, and the number of columns, and Fusion 360 will choose the right number of Gridfinity units.  Use the Change Parameters command, then edit the bit_rows and bit_columns parameters at the top.

You can also change the icon on the bin's long sides.  In the timeline at the bottom of the window, there is a row of features that are greyed out.  Activate exactly one of them by right-clicking and selecting “Unsuppress Feature” from the pop-up.  Deactivate all the others with “Suppress Feature”.  The icon on the back side will change to match.

How to Print

If you want to print the hole outlines and icon backgrounds in a second color as shown in the photos, you'll have to use multimaterial painting.  Hint: in PrusaSlicer, use the Smart Fill tool and set Smart Fill Angle to 43°.  Then you can fill a whole outline with one click.

The model is optimized for 0.2mm layer height.  The perimeters, infill, and material shouldn't matter.
