The Micron magbed is machined out of 6.35mm thick 5083 Aluminum Cast Tooling plate and is 160mm^2. We've used the specified hole layout available on the github. This is a top magnet designed bed and has incredible holding power with it's N48SH neodynium magnets good up to 150C are attached to the bed with countersunk screws . The magnets are recessed slightly below the surface of the bed. They have a pulling force of 11 lbs.We also added a center hole for those of you who decide to use the kinematics! Comes with 150C magnets standard. Please Note: We make the Micron beds when the order arrives, so there is a 3-5 day lead time on these beds before we can ship. Flex Plate Choices: Our magbeds are a top magnet design bed, meaning that the magnets are slightly below the surface of the magbed. This gives a very superior holding power, however, it does require a very good quality build plate, such as Buildtak or KB3Ds. The manufacturers of those flex plates use a 0.5mm thick sheet. Thinner sheets may dimple slightly under the magnet. A lot of China build plates are not up to the challenge. IMPORTANT NOTE: If at any point you decide to remove the magnets, first of all, when reinstalling the screws, turn the screw backwards until you feel the threads in the screw jump the threads in the bed. Once you feel that little bump, turn the screw in until it gets to the "screw stops turning point" with zero strength behind it. Once the screw has stopped turning, tighten it 1/32nd of a turn and NO MORE. Overtightening WILL shatter the magnets.
