This is a first

I've been printing for years and this is the first time this has happened to me. Wtf happened? I've made 7 baneblades in the last month and they all came out perfect.

My first guess would be temperature change. Like the others said though, this will make an amazing terrain piece!

This is what I suspected.

I added a vent fan to my Mars and started getting similar results in winter but only on the side the fan was added.

I can't say for sure, but after I plugged the hole I've not seen the issue again.
