I have 3 printers with upgraded printer beds printing this design. I couldnt get it to work with the standard bed. I have borosilicate glass and PEI plastic on 2, and 1 with a wham bam system. 1 printer has enhanced springs from gulf coast robotics for around $3. I would buy 2 more but they are sold out. I prefer the borosilicate glass and PEI plastic combo to the wham bam system, and also the borosilicate glass + PEI plastic sheet are both available at Amazon.I used Simplify3d software and it asked me to convert the print from inches to metric. Once I did that it resized it to full size.Does anyone know anyone in the United States in a psychiatric institution or other mental health facility who would like one free of charge? I will pay for shipping. My email is andy@greenrobot.com and my number is 724-GREEN-RO. I have 20 available at present with a few more being made each day.It takes around 4.5 hours for each face shield to print.
