This works very well on the glass bed of my Ender 3 Pro.

The enclosure is much larger than it needs to be for the stock Ender 3 Pro. It gives plenty of extra room for the additional filament guide and other add-ons that I have used to customize the printer.Rugged fabric. Make sure you push the tubes fully into the corner brackets.

Didn't think this would be worth it at first but low and behold. It's my new favorite bed. This with magigoo to add even more adhesion and then removing the magnetic plate from the bed after the print is done definitely helps removal.

Same magnetic mat that came with ender 3 pro

Update 3/15/2022: PLA sticks well, but PetG wouldn't let go! I'll have to experiment with lower bed temps to see if I can use it with PetG. Still love this surface! PLA goes down and doesn't move until you pop it off when the print is done.Original Review:I've been frustrated for a long time trying to get prints to stick to an after market CCTREE Ultrabase platform for the Ender 3 pro heated bed. I replaced it with this Creality Original Ultra Removable Magnetic 3D Printer Build Surface and now PLA sticks like glue.All those circles in the attached picture stick like glue thanks to this magnetic build surface!

Bought this for the price, and you get what you pay for. No magnetic adhesion on the first one nor the replacement sent. One star because there no zero stars. useless. Go with the original just a couple of bucks more and avoid the time wasted repacking and returning this piece of rubbish.

When I took the first part off of it. It stretched out and now it won't lay flat at all. Not to mention the magnet barely holds. I used the original for 2 years this one lasted one print.

I printed a lid for a clock weight and COULD NOT REMOVE the print .... at all .. tried reheating the bed, thru it in deep freeze .. no go. Heated bed to 110 .. no go. Ruined the part and had to pitch the print surface. Will try one more, if I have the same problem I'll us another brand and/or switch to glass. The original lasted a good 4 months with lots of use .. last one I ordered .. maybe 2 months. This one 1 print ..

When installing there was an adhesive magnetic sticker side to put on the build plate that was put on with no problem and no bubbles or any defects, but after setting the actual magnetic plate on and warming up the plate and leveling nothing printed as they should of if just printing on the default one on printer I ended up finding bubbles forming under the adhesive side as if heating and cooling was causing the expansion and contacting of the material off setting the plate leveling

Troubleshooting all the bad reviews: User Error!It is two sheets. Remove glass, peel apart top mat and bottom. Remove yellow wax paper and stick that sucker on after you figure out the direction the magnets are printed.Magnetic sheets are printed in horizontal lines. If it doesn't stick, turn it 90 degrees and try again. It bonds solid!Printing on glass was hit and miss for me. PLA sticks to it as if they are made for each other. Remove the top mat, flex and enjoy the crackle of your print coming off the surface.A must have along with your glass for other mediums.
