Pint (16 oz.) Mason Jar Cover

This is a cover that will prevent most of the light out of your large mouth mason jar, preventing algae growth. Th window on one side lets you easily see how much water is in the jar.

There are other designs out there, but I wanted something sturdy that would print in less time. This one was designed with that goal in mind.

I printed this on a Prusa MK3S with a .6 Revo nozzle and black Sunlu PETG. With a .3mm layer height (.2mm first layer), 15% concentric infill, .84mm extrusion width, 2 perimeters and print speed at 120%, this prints in 80-90 minutes.
