Z-axis shim thinned out enough to fit behind the dreamer 3d printer. As the dreamer is a bit more cramped inside this was needed especially if someone wanted to install a glass bed in their dreamer as the shim shipped with the dreamer(at least i thought it was the shim) doesn't seem to install anywhere. johngiachero is to be given full credit this is just a slight modification of his design along with his SCAD file to get it go to his THING page to remix it to your 3Dprinter or other sized glass beds.I printed this with a flash forge dreamer in 1.75 blue PLA at .30mm first layer .20mm rest 3 shells 25% hexagon infill,100mm/s print speed 120mm/s travel speed, 60C heated kapton tape bed 195-200C extruder with airflow on it,skirt on flashprint software. Install it right under the height sensor for the z -axis on the build plate support and between the z-axis supports
