Magnetic build plate and bed leveling object

DIY Magnetic build plate Update February 15, 2018: I am using an "Additional BuildTak FlexPlate" , https://www.buildtak.com/product/flexplate/ ,with PEI mounted on it. The original magnetic sheets mounted on the build plate remains intact. It holds great and there will be no horizontal slippage. However when I printed a large box with thick walls taking up almost the whole build area, I needed to add clips to prevent the print from lifting the corner of the flexplate. There is no problem with normal prints. The clips are only needed when there is potential of prints warping when they are close to the edges of the magnetic plate. So, this is my final material list and I don't anticipate any more changes. 1) Additional BuildTak FlexPlate, https://www.buildtak.com/product/flexplate/ 2) Gizmo Dorks PEI Sheet 12" x 12" 1 mm, https://www.amazon.com/gp/product/B074XLD5QH 3) Corneria 10 Magnetic Sheets Adhesive 20 Mil Magnet, https://www.amazon.com/gp/product/B003XNAHMC If the amazon links don't take you to the product, copy the link text and paste it in your browser or search amazon for the descriptive text. Right now Thingiverse is doing something to the links so they don't take you to the product page. Update December 18, 2017 I tested a large print, 260 x 295mm, with the PEI and it worked well. Once the magnetic PEI was lifted from the build plate the part just peeled off. The corner started to separate between the magnetic sheets so I put a clip on it. For large prints that are close to the corners it is advisable to use clips. https://youtu.be/x4u3nnKkihU Update November 29, 2017: I have upgraded the build material to use PEI. It works great and lets me print PLA and ABS without glue stick or hair spray. The prints are so easy to remove when completed. This PEI is 1mm thin and is perfect to use with the magnetic sheets. https://www.amazon.com/gp/product/B074XLD5QH/ . I tried using a 12 x 24 x 30mil magnetic sheet cut in half, hoping to avoid piecing the 8x10 material I used before. But the magnetic strength was poor and the adhesive was week. So, I used the same magnetic sheets, pieced together, that I have described below. The video of this can be found at: https://youtu.be/S6XliO3rpnk Original post, November 8, 2017: I have a Maghold system on my QIDI Tech 1 and love it. I wanted something similar for my new CR-10S. I decided to make my own with https://www.amazon.com/gp/product/B073TW738G Athorbot build surface and https://www.amazon.com/gp/product/B003XNAHMC adhesive magnetic sheets. I'm sure most build surfaces and most magnetic sheets will work just fine. I also got a sheet of 0.03" polycarbonate (lexan) in case I need more stiffening, but the mag sheets attached directly to the build surface seems to work just fine. I ditched the glass plate that came with the CR-10S and put the mag sheet directly on the aluminum bed. The bed seems to be a bit flatter without the extra weight of the glass bed. The glass plate weighs 919g while build surface with mag sheet weighs just 237g. I use a coat of glue stick or hair spray to ensure the prints stick nicely. I've been using this for a few days and really like it. I'm using it with a bed temperature of 60C and don't know how well it'll hold up for high bed temps. Make sure the magnetic surfaces align the same way. If you look carefully at the magnetic side of the sheet you should see some regular linear pattern. This pattern should go the same way on both the bed and the build surface for all pieces. The bed leveling objects make it easy to fine tune bed leveling. The cylinder is 25mm diameter with 1.6mm wall thickness and 0.2mm height. So you can check adhesion and fill for the first layer of your 3D printer. I copy to make five objects in my slicer, one for each of the leveling screws and one in the center of the Creality 10S 3D printer. https://www.youtube.com/watch?v=ZGxUAbYhKrc&feature=youtu.be
