Multi-color Single layer engrave testpiece

thingiverse

Print this speed limit sign with three colors by utilizing two intermediate filament changes. Be cautious as the extruder and bed will remain hot during filament exchange. For optimal results, heat the bed to 80 degrees Centigrade when using a glass bed with PLA. Begin by printing either the one-layer circumference (circle) or the speed limit (50). Remove the Gcode that cools the bed and extruder if needed. After the print stops, remove the skirt and change the filament. Repeat this process for the other insert and then the final piece in white, which covers all previous prints on the bed. Zero the bed and extruder temperatures and wait for the bed to cool down. Note that the white layer will be slightly transparent, so ensure engravings are darker. Visit www.3daybreaker.blogspot.com for more information. Thomas
