This pyramid have the same functionality as the original made by SpierceTech, nevertheless this version has less material, so you will waste less filament printing it and will have the result faster than the original model.
Other advantage is that the hole base let you check the result from the other side. This design is perfect not only for check your printer quality, it is perfect too for check the functionality of your fan layer.
I wish it will be usefull for your tests!
