Front cover for the Ultimaker 3 Extended. Designed for .093” thick Plexiglas or lexan. I do not know the opening dimensions for the regular Ultimaker 3 for cutting the Plexiglas/lexan. I imagine 100mm less in length would work. When not in use, the cover can hang on the side of the machine. Note: Custom text will be added upon request, just ask.
