Ender 3 Corner Bracket

thingiverse

Manse84 had an impressive design, but they either never completed it or failed to update it with the final version. I strongly dislike attaching binder clips to my bed for all the reasons that come with it. Manse's corner bracket was nearly perfect, but the bed still slid around unless shimmed. The problem lay in the lack of 1mm or extra material between the edge of the bracket and the bed. To solve this issue, I added that necessary material, and now three brackets hold my glass bed firmly in place. Occasionally, some materials or prints refuse to stick to the glass bed, so I place a Creality original fake buildtak build plate on top of my glass bed. This setup has just enough lip at the top to secure both without any concerns. If you prefer a lip that is completely flush with the build surface, stop printing (or shave off) the top 2mm of the bracket.
