Building or repairing a 3D printer, CNC machine, or any project using NEMA 17 stepper motors?

This simple mounting plate is an essential little piece of hardware.
It's made from black anodized aluminum (6063-T6 grade), so it's strong, lightweight, and looks clean.
The design is clever: it has a slotted hole, which is super useful because it lets you adjust the position of the motor to get the perfect belt tension.

There are also multiple mounting holes to fit different motor and frame configurations.
It's basically the interface that lets you securely attach a standard NEMA 17 stepper motor to a V-slot aluminum extrusion (a very common framing system in DIY machines).

Installation is straightforward – just line up the holes and screw it together.

Having a proper, rigid mount like this is key for reducing vibration and ensuring accurate movement in your machine.
One plate per package.

A small but vital upgrade for smoother printer operation.
