Hi! With whatever respect you think you’re due with my honesty, I dont need suggestions on how to successfully use my 3D printer. My bed is free of finger prints, etc etc. My review on your print is accurate to whatever profile I used of it. You should therefore direct comments about how to improve the profile to the person that uploaded it (vs me, someone who simply used the profile) or disable the ability for people to upload different slices of your creation. My rating will remain as something based on whatever profile I use. Hope this helps!
