I designed this screwdriver stand years ago to help organize my electronics workbench.  It is a fully parametric design and allows for many different sizes to be generated.

Originally only the part with the top plate and legs was part of the design, but I found that this started sagging a bit when a larger number of tools was used.  Recently I printed a larger size and added the option of having the extra support shelf available.  This also comes with the advantage that the screwdrivers are less likely to tip over.  The shelf is printed separately and can be attached with some CA glue.

While printing the version shown on the pictures my blue PETG-HF got tangled and I continued the print in red.  In all, it came out quite nicely and I decided to keep it this way!  If you want the same effect this is easy to set up in the slicer.

With the updated design, the number of holes, sizes of holes, height of the overall stand, and the height of the shelf can be selected.  So if you make the holes bigger you could even use this as a test-tube stand or find some other creative application.
