This will securely hold an M18 random orbital sander and should work with most other brands as well.

I recommend printing with four or so parameters for strength. No supports are necessary. The included holes are sized for #6 wood screws.

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
