GCW Zero D-Pad and Button Update
Some of the early Zero units suffered from d-pad and button rubbing. There were a variety of community solutions, but the one everyone hoped for were replacement parts. After many model revisions and test prints, 3D printed replacement parts have finally arrived for the Zero. The source article below provides an in-depth synopsis on the process and the replacement parts. The d-pad and buttons cost $6.50 and $3.50, respectively.
