The threaded ring on my pool table light broke, so to the printer!

I checked the temperature of a 60W incandescent light bulb, in the fixture, and it got the area up to about 200 F. Since PLA is melted at about 200 C, it should be ok with incandescent...

BUT

I suggest using an LED bulb in the fixture anyway, just to be safe. The temp is only about 100 F, so nowhere near the limits of PLA.
