Here is another version of a Boardman Bee Feeder. After originally printing the beefeeder by TheHeadlessSourceMan https://www.thingiverse.com/thing:269229 , I realized that I wanted a larger feeder that incorporates interchangeable jars, for the jar threads tend to stick to the PLA layers.

This design uses standard WIDE mouth quart jar lids (~86 mm or 3 and 3/8 inch Jar mouth), which rest inside the feeder up to the neck.

Simply place the feeder into the entrance of the hive, puncture a few holes into a canning jar's lid, and invert the lidded jar onto the feeder.

Please let me know how yours turns out!

As requested, I have added a couple more designs with shortened entrance tunnels, which should accommodate more printers.

Total lengths: Original: 200.5 mm long Shortened_1: 190.5 mm long Shortened_2: 170.5 mm long

Feel free to request more changes, anyone.
