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 (which I’m not releasing yet), 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.
