Nuc entrance disk

I recreated a nuc entrance disc, but with larger ventilation holes that are easier to print and less likely to clogg. Beware: these aren't some sort of queen or drone excluder holes. Regular workers shouldn't be able to pass either; they're too small.

Also, I've provided an entrance variation that will accomodate 16mm tubing, if you'd wanted to put the nuc in an isolated / warmer environment and create an exit outside (like place the nuc in a greenhouse with a 'remote' entrance outside.

I haven't used this feature yet, so please let me know if it works. As long as it isn't tested it's just a hollow knob for rotating the disc.

Update:
Since I didn't need the tubing entrance, I added an entrance with queen excluder bars, increased the openings and added a knob.
