STEPPERONLINE NEMA 17 Stepper Motor (Economy Geared Stepper Motor) Alloy Steel Mounting Bracket ST-M1

If you have one of their Geared stepper motors, you need a bracket like this - either to mount directly and/or use as a template. very sturdy and up to specs.

It fits the economy gear motor perfectly, with absolutely no play once it's bolted in. It's well-dimensioned, not too heavy despite its steel construction, and provides enough space under the motor and gearbox to hold a nut.

Fits both the standard stepper and the one with the gearbox perfectly, no issues

this is a NICE mount. it is very sturdy I Will buy another for my next project! just you wait!

This was an impulse purchase after I placed an order for a matching stepper motor, but I was not paying attention to the slot direction. i don't really understand why most of these have slots going parallel to an attached motor shaft. usually any pulley can provide an adjustment it that direction, but if the slots are perpendicular then you can use the slots for belt tensioning.

I am posting the first photo in case it might be helpful for somebody else. I purchased this unit intending to use it with a device I invented to measure a person's eyes 8 or more feet away (see second photo). I couldn't fit it into the design of this product. I ended up taking another approach and returned this device.

The brackets that I received were not close enough to square for reliable linear motion. I bought these to mount motors in building a 3D printer and have had continuous alignment issues that have needed to be painstakingly shimmed out. I determined that most of these issues are caused because the brackets are less than 90 degrees causing misalignment with other linear motion components. So I will now be printing my own brackets to improve my machine.

Not sure if I could ever "love" a bracket, which is why these only got 4 stars. But they're nicely made, well finished, and fit the motors they're made for. Nice and solid as well.
