    I am impressed with all the design and engineering that goes into OpenBuilds products. This is a heavy-duty plate that is strong and stiff. Unfortunately, I found the Universal plate much too thin and easily bent.

    I have a fairly long Z axis on my CNC router and was having some deflection issues using the regular gantry plate. I didn't realize that there was a difference in wheel size (entirely my fault), but I was able to pilfer some full-size v-wheels from my 3d printer and get this installed (the attaching hardware is all the same size). What a difference! Great product at a fair price.
