Fabrikator mini magnetic print bed bracket

thingiverse

Human: I've designed magnetic attached brackets for the print bed on my fabrikator mini, one stays attached to the printer, the other to the bed, 3 variations can be generated depending if you want keying or not, designed around 6x4mm cylindrical magnets. I'm using a keyed set for the back brackets and a non-keyed set for the front, this is working really well so far! You'll find that you need to adjust the z-axis, I might design a better z-axis end-stop mount as this has highlighted how much of a pain the stock design is. Here are some installation instructions: Installing the brackets to the bed is pretty straightforward, but installing the brackets to the carriage and installing the magnets can be tricky. First things first, you may need to drill holes for the magnets, which can make them a little loose - if this happens, push the magnet halfway through the front and apply superglue to the back before pushing the magnets flush again, this will ensure some of it gets down the sides and gets a good fix. Installing the brackets to the bed can be a pain in the neck, I removed the front for access, then removed the clips holding in the smooth rods on one side - I could then slide them out to release the carriage. Reassembly is the opposite of disassembly! Getting it on and off the belt is also a bit of a challenge. Edit: 19/11/2016 I installed the brackets and made a test print, so far so good (but don't forget to adjust the z-axis)! Edit: 20/11/2016 It works as planned, no major issues - it has reinforced the need for a better z-axis endstop arrangement though, that screw is a real pain to get to and it doesn't stay put for long, something attached to the front or side panel makes much more sense.
