I suggest printing it at 0.3mm layer heights so it threads snug but not too snug.

Edit: Added a new .20-1 size for greater nozzle support, and two lids for dust protection. The lid top is 0.4mm thick, so you should be able to have a pretty good "clear" viewing hole even with FDM printing if you nail your settings.

Edit2: More stuff.
