Whilst the acrylic frame is easy to build its not that strong. I wanted to clamp it to my desktop, so made these mounts. Remixed the z-switch homing of http://www.thingiverse.com/thing:640943/#files to attach to the z motor clamp. Get the original z-endstop adjuster from here. Works great - although now replaced with induction sensor for the z home.Printed at 40% infill Used support for the mount with the switch holder
