Ước gì cái này là Packout

Turn anything into packout with these mounting cleats. 

Printed with PLA, works well in ABS too. 
Make and sell if you'd like, there's a good market for these. 
If you want them altered let me know and i'll see what I can do. 
Altered some random STL's I found in tinkercad. 
Gave them more strength and made it a more snug fit.
Altered to suit my socket set and make it packout compatible.
Made them all thicker
More infill for strength
The latch is widened and shortened
Added mounting female mounting feet because Milwaukee's unrealistic with pricing on their wall pates.
