What was the actual issue with the insect hotel one?

Are the winners chosen by prusa or just on public votes?

Either way, I’m not sure that they should have to moderate all the entries, just the ones that win (within reason)

I love my prusa mini, but if your using it for practical stuff, the size of it’s build area can be limiting.

Buying online is probably easiest.

I can’t speak about the printer choices (I have a prusa mini), but I can talk a little about miniature printing.

At the level of detail you probably want, filament dryness is vital. Damp filament strings loads and generally doesn’t print cleanly, losing you all the detail.

When you start off, you should be fine as long as you put your spools back in their bag with the dessicant pouches (could be worth buying more). But once you can, either making/getting a dry box or buying a filament dryer is probably worth it.
