Ender 3 Corner Bracket

thingiverse

Manse84 had a gread design, but they either never finished it, or never updated the thing with the final iteration. I HATE putting binder clips on my bed, for all the reasons. Manse's corner bracket was 99% of the way there, but the bed would still slide around unless shimmed. The braces lacked 1mm or extra material between the edge of the bracket and the bed. I added that, and now 3 brackets hold my glass bed in place tight. I occasionally find that some materials or prints don't want to stick to the glass bed, so I throw my Creality original fake buildtak build plate on top my glass bed, and this has just enough lip at the top to hold both without worry. If you want a a lip that is completely flush with the build surface, stop printing (or shave off) the top 2mm of the bracket.
