A 3x1 Gridfinity Cocoa Press baking sheet holder.
A super flexible build plate calls for a different kind of Gridfinity build plate holder. This is wide enough to easily insert and remove the baking sheet and is high enough that it won't flop over.
The author remixed this model.
I split and scaled up the original model on the Z-axis a bit so the flexible silicon baking sheets wouldn't flop over.
