Slim Packout Bins for Milwaukee Bit Holders

Slim Packout Bins Hero Shot


Note: These are not a new design. I’ve just moved them to my site because Thingiverse has decided that it’s not going to let people download these for some reason.

These two low profile Packout bins are designed to accept the Milwaukee bit holders that come in their accessory cases. I’ve created two STL files that you can download and print: one small bin and one long bin.

The holders store flat in the bins and can be rotated 90° to access the bits. The bins have two rows of mounting holes, but you can’t have one holder directly below another, they need to be offset by 2 or 3 holes.

In the long bin photo I show above, the 2″ driver bits touch the longer drill bits, but they still lay flat enough that the lid will close.

The only issue that I’ve found with the bins is that they tend to scratch some material off the ends of the holders, I’m not sure if that’s because I printed them in PET-G or that maybe I should have used a smaller layer size than 0.2mm, but then they’d take longer to print.

UPDATE: Here are customizable bit holders for these bins



Printer: Prusa i3 MK3
Slicer: Cura Slicer
Material: Inland PET-G
Resolution: 0.2mm with a 0.4mm nozzle
Wall Lines/Perimeters: 3
Infill: Minimum 20% Gyroid. The higher infill percentage the stronger the part.
Notes: I printed these in PET-G and used a 20% Gyroid fill because I find PET-G doesn’t do well with fill patterns that overlap like grid.


  1. do you have a design that doesnt incorporate the bit holders? I would just like to be able to stack bins for in a deep organizer for finish nails as an example. I assume the bit holder bins would do the job, and I am not sure if adding the extra depth on the bins adds any additional value if I were not using the bit holders? Really impressive designs! Thanks alot for your time.

  2. Ive downloaded the files and can open in 360 but I can not seem to print it. I believe that I need to unzip and extract the files first but I am unable to do so. Any advice?

    1. Download the STL files and use a program like Cura, PrusaSlicer, Repitier, etc to print them.

      The models are just there for reference, if you want to try to make your own remix. You cannot do anything with them because Autodesk has locked down the free version of Fusion 360 so hard it is useless. You can only look at them.

  3. Thank you for all of this. Really has given me some ideas. What inexpensive 3D printer would you suggest for making these kind of things?

  4. Is anyone having issues with the prints stopping sporadically between 1/4 and 1/2 of the way during printing. Im sure it must be on my end, just curious…. Im a pretty novice printer so very well could be me!

    1. That could be a printer issue, but you want to check out the output of your Slicer to make sure there are no missing layers. Just use the layer slider (PrusaSlicer and Cura both have one) to make sure there actually is something there for each layer.

      I’ve found that sometimes PrusaSlicer will slice something incorrectly leaving big gaps, or give errors for an STL file that I know is fine. What I do then is restart PrusaSlicer, which usually fixes the issue. Or I’ll switch to Cura to slice that particular print.

  5. I’ve never 3d printed but this makes me want to start. What is a good entry level printer that I could use to print these? I worry if I buy one I will screw up and have something that doesn’t do what I want.

  6. Awesome work man, question, my son and I were admiring a bin and bit holder I printed today.

    Have you thought of using the existing bins and making an insert to fit into it? Into the integrated grooves in the bin. Son was thinking that would preventing to have to print so many bins.

    1. I actually did that as a proof of concept when I was designing the bins, I found that the walls of the stock bins were too flexible. Because of the divider grooves, I have to make six separate mounts and they didn’t stiffen the sides enough. It was a bigger problem in the middle. It was also really hard to line up the pieces so they were even on both sides. Yet another issue is that the stock bins have a 1 to 1.5 degree draft (the bottom is narrower than the top). You could account for that, but I just decided it was easier to make the bins.

      I actually have an rough openSCAD file that generates the pieces that you could tape into a stock bin and try. Send me a message via my contact form and I can send it to you.
