FlashForge Dreamer Z-axis Shim

thingiverse

My spin on the FlashForge Dreamer Z-axis shim. This setup is secured with stability in mind, utilizing two existing M3-0.5 x 8 mm socket head screws that are bolted down for maximum support. You may need a shim if you upgrade your build plate's thickness (for instance, by adding a glass surface on top). I have uploaded shims of 2 mm, 4 mm, and 6 mm thickness. Normally, precision is not required with shims because the leveling screws allow for long travel adjustments, so choosing a shim that gets you close enough will still let you fine-tune the plate later using the leveling screws. However, if you need a different thickness of shim, I've provided a CAD link below. Printing This part is small and requires attention to overheating. Note that I printed a tall skirt (as tall as the part) to distribute heat evenly. The raft was mainly used to hold the skirt in place. Installation It's helpful to have a 2.5 mm ballpoint allen wrench, similar to the one included with the Dreamer, since the screws are located in tight spaces and this type of wrench can be inserted at an angle for better access. Installation is demonstrated in the pictures.
