Milwaukee Packout Feet


***NOTE: Use at your own risk. While 3D printed parts can be very strong, they are only as good as the printer, filament, and settings you use. I would not recommend hanging significant weigh off these feet.

Let’s understand what a Packout foot is first. A Packout foot is used on the bottom of boxes, platforms, etc. to connect it with the top of another Packout box. Since it’s a protrusion on the bottom, it’s like a foot.

So why am I releasing a Packout foot when there are other feet out there like the Kaizen K’NEX mounting foot from Kaizen Inserts, or the multiple designs on Thingiverse? I wanted to make a locking Packout foot, but first I needed to create a model for a regular Packout foot.

Then I started getting some ideas of how I could fill in niches that haven’t been occupied like:

  • A wide foot (Big Foot) that fits into the middle slot on boxes.
  • A half foot (Little Foot) that only engages into one side to save printing time.
  • A thin foot (Thin Foot) that only increases the height by 1/4″.
  • Choices on how many holes, where to place them, and whether to use a countersink, counterbore, or even pressure sensitive tape.

So without further ado here’s some example STL files you can make with the openSCAD model. I’ve including the regular Packout foot, BigFoot, a zip for right and left little feet, and a ThinFoot.


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 10% Gyroid. The higher infill percentage the stronger the part.
Notes: Counterbore holes turn out cleaner if you use supports, otherwise supports aren’t needed.


If you don’t see the specific hole pattern you need (or want countersinks) you can create a custom STL using the instructions here, or contact me and I can add another file. You could also make say a Thin Big Foot or Thin Little Feet, there are too many possibilities to provide files for them all

All of the STL files with counterbores are made for #8 pan head screws. Here’s instructions on how to install the Packout feet. This will work with any size foot that used screws.

Step 1 Attach tape and place feet where you want them

Attach double sided sticky tape (or carpet tape) to the top of each foot and slide the feet in place under the tabs of the Packout box.

Step 2 Place over the feet and press down

Peel the backer off the tape and locate the box or platform like you want it positioned over the feet. Once it’s in the proper position press down hard to tape the feet in place.

Step 3 Predrill holes for screws

Slide the platform off the Packout and flip it upside down. Use a drill bit smaller than the screw you are using to drill pilot holes into the base. All of the STL files I’ve provided are for #8 pan head screws.

Step 4 Screw feet into place

Screw the feet into place.


  1. Hey! I was wondering if these feet would work for a tool box (for example a M12 wirsbro tool box) and mount the legs on them for the packout.

  2. Would this work on the bottom of the Packout Rolling Toolbox? Looking for a way to secure to my truck bed using the Milwuakee flat mount. Thanks a lot of great ideas posted.

    1. They might, but there could be several issues. The box wouldn’t sit flat anymore. The grid ribbing structure on the bottom would make it more difficult to mount them. And if you penetrate the bottom with screws, water can seep into the box from the bottom.

      These are not insurmountable problems, but they aren’t trivial either. Let me know if you try it, I’d like to see how it works.

  3. Hola, hay una manera de añadir estos pies a la mochila milwaukee (version anterior al packout)?

    1. This is what Google translated: “Hi, is there a way to add these feet to the milwaukee backpack (pre packout version)?”

      Because of the way it translated pre-packout, I’m not sure if you mean the 0885-20 backpack vacuum or the 0880-20 Wet/Dry vacuum. I have feet for the 0880-20 here:

      For the 0885-20 backpack vacuum, attaching feet to the bottom would be difficult and I’m not sure what it would accomplish. There’s not much space on the bottom of the vacuum to mount anything and it would be very hard to maneuver into place with the straps attached.

  4. Hi! These are awesome.

    Do you have any design for cleats to put on the top of another flat box? I have a couple of boxes I’d like to convert top and bottom for the Packout set.

    1. Do a Ctrl-F5 (Hard page refresh) and try it now.

      They file links weren’t pointing to the HTTPS link. Some browsers like to cause trouble when the page has mixed HTTP and HTTPS links. I thought I fixed all the instances, but I guess I missed these.

  5. Thank you very much. Printed these in ABS and they did not have to be adjusted for shrinkage. Fit like a glove 🙂

    1. I’m guessing you found them and it was you that remixed them on Thingiverse. Sorry I haven’t consistently shared my Fusion files in the past because Autodesk keeps changing the terms of the license. Sometimes I’ve only been able to share the files read only, which isn’t very useful.
