Wanted a temperature tower with some shapes built in so designed this one in Fusion 360. Has some simple shapes such as ellipse, circle, triangle, and squares along with a cone and pipe shape.

The base is 2mm, so keep that in mind for changing the temperature through your slicer. For example, the PLA tower starts at 220C so you would print at that temperature until the layer height reaches 12 mm and then have it change to 215C. Then at 22 mm have it change to 210C and so on.

Added model for PETG.

PLA (185-220) PLA Plus (190-230) PETG (230-260)
