Was getting tired of searching around my toolbox for my electric screwdriver and its bits so I figured it was time to design a nice simple stand with space for my most used bits. I decided to give it a tray just to help with not losing screws. The project was modelled up in blender in an hour or so using a mix of sub-d and boolean workflow. The stand printed out nice on my old dependable ender-3 in about 6 hours. I did a number of test prints of just the holes so that I could get the fit right. Getting The bit holes right took time as my printers accuracy is just a bit off and different bits had extremely small differences in dimension. The bit holes actually taper slightly so that the gradually become .5 mm smaller. This saved me having to throw out a whole print if I got it wrong.

So far it’s met my goals. I have some changes I’d like to do if I ever reprint:

1. add compartments or seperators to the tray so I can use them as “steps” to aid in re-assembly of projects.
2. add more space between the bits and the driver holder in the center. My finger can’t get between there and it makes it hard to pull out the bits.
3. make a base with a bearing so the whole thing spins.
4. make a notch on the top so the driver can rest horizontal. No real reason just a nice feature that would add to the utility.
