    As @Science.Buddies mentioned in response to @BiscuitBricks asking for a part list to build this, the model can be varied slightly by using various different pieces depending on what you have available to you. This Parts List was made by me simply counting the pieces as they're seen in this video. Some items' counts (for example, Black Chain Clips) are a guesstimate, made by counting what could be seen and making an educated guess as to the number of additional pieces that would be required to cover the space that stays hidden behind other pieces and prevents me from seeing all of the parts I'm counting. Others are the total overall count of that piece accounting for each particular location it was seen in throughout the video. While it appeared that the same completed model was being shown at different points throughout the video, various new pieces were added or existing pieces were removed/rearranged. This just goes to show the truth in the variability of pieces needed for building this model. Furthermore, there are many pieces which can be swapped and used in place of another, just like the Red and Metallic Green Rods. For instance, in many (but not all) places where the Blue Rod End Clip is used by clipping it onto the side of a rod as opposed to the end, a Grey Spacer may be used instead. And a good number of Blue Spacers I counted being used in the video aren't really necessary. Taking all that into consideration, all counts are +/- a few.

    This is incredibly helpful, thank you for taking the time to count! We will pin this comment so hopefully others can see it.

    Unfortunately we didn't count all the individual parts required to make this, but you should be able to vary the design based on the pieces you have available.
