Milwaukee Packout foot/base

I created this base plate design to be used with the Milwaukee Packout tool boxes.
My plan is to attach these to items such as other tool boxes, radios, a worktop, etc to the Packout containers. I plan to design the larger base in the future but so far these small ones have worked great.
You can print them at whatever you like but .35 mm (Fast) is my preferred setting with infill depending on needed strength. 20% is usually strong enough but add plenty more if you plan to tap them. I have been using hot glue to great success.
I Print them with "supports from bed only".
*** As suggested by T3rry in the comments, print upside down and you will not need supports. This was my first build on a 3D printer so I missed that in the original.
This is my first project in 3-D printing and with Fusion 360. =)
