If you have any problem with your print work like can't make the filament sticking your bed or hard to remove your print out of the bed.
I don't know what you think but to me, this is the best thing that helps me printed a lot. It's the MAGNETIC 3D PRINT BED. It's easy to install. It has a flexible mat that has a magnetic side and a side that’s designed for the print to confidently stick to. It sticks very good and special thank to the flexible print surface, when your print has done you can remove the mat and simply bend it away from the print to separate them.
I don't good at present so it all I want to say. If you don't believe me just buy it to try it
