PETG Nozzle Wipe Tower

This STL can be added to a print in Prusa Slicer for any 0.2mm layer height print and it will clean the nozzle of PETG gunk. I noticed that on repetitive larger prints, the PETG booger would generally fall off in the same place, damaging the print. So I made an object that enourages boogers to fall off in it so they don't fall of in your valuable print. Think of it like a sacrificial booger tower.

Prucer Slicer over extrudes narrow sections of 100% rectilinear infill, possibly due to it overlapping with the perimeters. This means the PETG will climb up the nozzle but it also means as it moves in a line, an already gunked PETG is dragged off. It is not perfect, but it tends to be enough so that when a booger falls of, it does so in the tower.

The tower is designed with a solid track of 100% infill with gaps in it. Without the gaps. the tracks overflow and will eventually cause a nozzle crash.

The tower only works for 0.2mm layer height prints and the special settings this objec
