I created this model to put the build plates on after a print to let it cool off quicker so that models are easier to remove; since the top edges are pointy, there's minimal contact with the build plate, so increased airflow on both sides of the build plate.
I also think it's a cool looking shape :P
Here's a time-lapse of the print (more info at some point in the future about how the time-lapse was made, will update this once the info exists).
This was modelled in OnShape, the source file is available at this link.
The author marked this model as their own original creation.
