Are you tired of waiting for your print to cool?
Tired of trying to get your print off your excess application of glue stick?
Sick of buying replacement magnetic sheets for your ender3?
Don't you just wish you had an Original Prusa i3 with its powder-coated PEI spring steel sheet, with its effortless and time-saving print removal? (This is starting to sound like a TV ad isn't int! All we need is a buy 2 get 3 free deal!)
Well, now you can buy these clone PEI powder-coated spring steel sheets from Banggood in all the popular sizes (220x220mm, 235x235mm, 254x241mm (Prusa i3), and 300x300mm), in black, gold and smooth (PEI sticker) versions.
It would be much appreciated if you use these affiliate links below when (if) you buy one, it doesn't cost you anything and it helps make it worth my while doing these things for everyone.

Step 1: Fitting the Magnetic Sticker
While you can buy these sheets with six 20mm rare earth magnets, I prefer to use the ones with the magnetic sticker, it is plenty strong enough to hold the steel plate and resist knocks with the print head, is much easier to fit (The round magnets require the removal of the heated bed), and doesn't mess with inductive and capacitive auto bed levelling probes.
Also in my testing, it doesn't seem to lose its magnetism over time like the creality easy-peelzy style magnetic sheets (Where the actual sheet itself is magnetic).
So, how do you fit it? First, you will need to thoroughly clean the heated bed, or if you are using an older style FR4 PCB heater you will need to stick the magnetic sheet to a piece of glass.
Simply peel back the protective paper along the back edge of the magnetic sheet (about a quarter of the way should do), then very carefully (Don't stick it down yet) align the back edge of the magnetic sheet with the back edge of the heated bed.
Make sure that the edges are aligned as closely as possible as this will determine how straight the sticker is compared to the heated bed.
Then, while slowly pulling out the protective paper, press the magnetic sheet into the heated bed, working from side to side to get an even "stick".
Trim any unnecessary overhangs with a pair of flush cutters or a craft knife, And you're done!
Now you can print quicker and easier than ever before, and all from just 30 US dollars... =)
