Dishwasher Rack Protectors in PETG

Our standard dishwasher loadout changed a while back, so I ran off more protectors to fill the bottom rack. The crystalline look of natural PETG is probably wasted in there, even though it puts the old, rather yellowed, PLA protectors to shame:

Dollops of silicone sealant hold them in place: the bigger the blob, the better the job.

We don’t activate the drying heater, so the plastic doesn’t get exposed to absurdly high temperatures. As nearly as I can tell, those PLA protectors remain in fine physical condition, even though they’re turning an odd color.

The support structures peeled out easily with a fingernail pull:

PETG doesn’t bridge well, as shown by the gaps between the support ridges. Those 0.20 mm layers seemed skimpy for lightly supported PETG, so I ran another set at 0.25 mm:

Not quite enough improvement for a Happy Dance, although fine for the application.

We look forward to seeing what grows in those little crevices…
