"Airport" mason jar lid hole template

Mason jar lids with ports and filters are used in mycology for grain inoculation and spawning liquid cultures. This template for aligning drill holes and easy placement of stick-on injection ports and filters. This template is designed specifically for these generic reusable mason jar lids from Amazon. There is one template for standard & one for wide mouth jars. If you find these templates work for other lid brands, please leave a comment. I've included a parametric file so you can adjust for other lids (Please post any remixes)! 

The default drill holes are ¼". The injection port cutout is 18mm, and the filter disk cutout is 20mm. If you stick the injection port on first, it keeps the template in place while applying the filter. The injection port cutout is marked with the syringe icon.

UPDATE: At the request of @KristusApollo_301 I've added variants that use 18mm for both the injection port and the filter disk. Both have been printed and verified.
