Ergonomic Chair Bracket

thingiverse

The odds of anyone else needing or wanting this part are probably pretty low. However, if you do happen to own a WorkPro Commercial Mesh Back Executive Chair, and the lower bracket that connects the spring loaded lumbar support to the seat has broken, this is a carefully redesigned part that can be used to replace it. It's still a prototype, as I've only been using the replacement for about a week. I printed mine initially with PETG, but am planning to reprint it with Nylon or ABS for durability. Two small indents in the sides are for the spring to slip into, you must drill through the side at that location for the springs to slip in. I used a 1/8" drill bit. ### ⚠️ Important ⚠️ Because this part is designed to flex at the point it contacts the metal bracket as you apply pressure to the lower back, it's important that you print this on it's side to reduce the chances of layer separation causing the part to break (as it has for me twice now).
