This is a tongue in cheek warning sign for those dangerous machines. This is not printed on one of those fancy multi color machines, it is only taking use of manually adding color changes (available in prusa slicer) and manually swapping filament colors.
I chose white for the base, did a color change to orange @ 5.7 mm, then a swap to black @ 6.6mm.
Added new versions, both thinner. The thin marked model has no magnet holes, and is for say 2 sided tape mount.
The new heights for the magnetic model has an overall height of 5.6, with color changes of 3.8 & 4.7 mm.
The thin model is overall height of 4.1, with color changes at 2.3 & 3.2 mm heights. Note, becaus it is thinner, make sure it fully cools before removing from the bed to prevent warpage.
The author marked this model as their own original creation.
