I designed this top mount Build Plate holder for the A1 MINI to keep my desk more organized. You simply remove your Z axis outer and inner caps and install this using the original screws. I made the slots a little on the bigger side to allow it to fit holographic plates. With a full stack of plates in it, I only ever hear any noises when its doing the bed vibrations before prints. Another TIP is to carefully use the metal scraper to assist in removing all of the support material from the big flat area.
