Hex Shank Bits Holder
This is a remix of the hex bit holder by TBRIshtar :
http://www.thingiverse.com/thing:241501 - thanks TBRIshtar!
Update 2018/05/07 Added new options under the advanced menu to:
- Modify the spacing between row and column holes
- Select between hex or round holes
- Set the amount of space from the hole edges to the holder edges - can be set individually for row and column edges which allows for either or both side holes to be cut "open" on the edges.
- Set the hole diameter
- Set the corner fillet radius
Update 2017/10/31 This thing is now customizable using the Thingiverse customizer.
This remix mimics the original as close as possible but has the following
- Almost fully parametric
- Any number of rows and columns, still keeping the edge rows open on the
sides. This is nice if the hex shank has the bit size stamped on it.
- Footer height can be adjusted
- Wall height can be adjusted
- Allows easy scaling in the X and Y directions if your printer causes
the hex holes to be too tight, like mine does.
I use the OpenSCAD fillets lib https://github.com/jfhbrook/openscad-fillets
by jhfbrook for filleting the edges - Thanks jhfbrook!
Holder() module takes all dimensional parameters as arguments, so can
easily be used from other SCAD files.
The original size of the holder by TBRIshtar are the defaults, but simply
override any dimensions you want in subsequent variables of the same name, or
change the originals.
Another quick way to generate STLs for any size is from the command line:
$ openscad -o output.stl -Dcolumns=7 -Dfoot=3 -D scl=1 bitHolder.scad
Note when using the command line you must supply the
scl variable if you
do not want any scaling. This is because the file overrides the default scale
from 1.0 to a scaling I use on my printer. The same goes for

I set my walls (cura) to 1.6mm and no infill so it basically just prints the walls. Works quite well for me!
