    End Cap

    I purchased this for a DIY CNC project machine. It arrived faster then anticipated and the packaging was very nicely done. I haven't used the product yet but close inspection gives away that it surpasses similar products via. Amazon. I'm still considering buying the offset version of this just because it conceals the motor. But either one it good.

    Great Quality

    Fit and finish are perfect. Gently rounded edges provide a nice touch to not rip your skin open if you happen to run into the corner of your machine. Threads are clean and spot on. The 4-point motor mounts provide a really nice assurance for exact fit of the motor and 4-post stability for any torque or collision concerns. I do wish these were thicker like the C-Beam end mounts are though. There is a significant different between the two so you have to account for that in your design (extrusion length, lead screw length, etc). I ended up choosing these for everywhere I have a motor because of the 4-post mount, but still am using the C-Beam End Mount on the opposing end.

    Cool plate! It is already drilled to accept a Nema 23 motor.
