I kept having problems with big prints shifting on the automated build platform, and I heard it might be because the belt isnt completely attached to the platform. So what I did was create flaps that went over the belt to keep it from moving upward during a print. I have attached them, but have yet to print out a large object. (Also, I have only printed out the middle ones for use, but I also made ones to go on the corners)I have prints for the middle screws, BLFR (Back-left, Front-right), and BRFL (Back-right, Front-left). Print whichever ones you want depending on where you want to attach the flaps.NOTE: These flaps COVER PART OF THE BUILD PLATFORM. While it is a very small amount, make sure your prints are small enough that the extruder wont run into these.EDIT: Someone mentioned that this might stick to the belt after awhile because of the heat. If this happens to me, I will be sure to post it. Also, because the build platform doesn't get as high as the extruder does, only around 125C, I believe it should be fine. Only concern I would have is it might eventually warp from heating/cooling alot.Print. Hole may need to be widened for screws to fit. Unscrew side screws on build platform, replace with the M3x16 screws (the M3x12 are too short) Screws go through the print, then are screwed back into their original holes.Note: Print may not be wide enough to cover the belt, but thats ok, because these can be rotated to slide over the belt.
