This model makes the following improvements on the colorpod (https://www.youmagine.com/designs/colorpod-full-color-printer-module#information) design by Aad van der Geest: - Several parts that needed to be glued and screwed together combined into one - Mount for shaker motor integrated (no need for hot glue) - Rather than balancing the powder dispenser on a screw to allow it to vibrate, attaches it using thin plastic to the main model which has enough flexibility to allow the vibration - Powder funnel screws in (using printed threads); easier to print compared to Aad's funnel which just slides on top.
