This will securely hold an M18 7 ¼" circular saw and should work with most other brands as well.

Update 2/10/23: A user has reported that the mount is too narrow for his M18 2732-20, it does it my 2631-20 and a few other people are using it without isse with other unspecified Milwaukee saws. So there may be more variation in size between some models of saws than I was aware of.

I recommend printing with four or so parameters for strength. No supports are necessary. The included holes are sized for #6 wood screws. Assembly of the three components is trivial but will require glue.

I have designed other similar holders for a variety of M18 tools.

• Drill/Impact Driver
• Jigsaw
• Random Orbital Sander
• 7 ¼" Circular Saw
• Drill Side Handle
• Grinder
