    c beam gantry plate.

    Posted by Martin McClary on Jun 6th 2024

    I ordered a couple different sized plates for the C beam, as it's my first experience with something other than makerslide. These plates are a bargain when you consider the price of aluminum and the work that goes into them. The holes that are tapped are great and allow for some flexibility in the build.

    Openbuilds countersink holes are more accurate than China

    Posted by David Suffield on Feb 1st 2023

    I had to replace the c-beam double wide gantry plate I bought from China with Openbuilds double wide plate because the countersink holes on the China plate where not deep enough to clear the low profile bolt heads.
