Pretty cool. Nice project for kids and bird lovers alike! Gonna try printing one or two up this weekend. Thanks!

Thank you for the kind words. I hope your kids and the birds like the feeders.

I needed a drinker for birds and I did not notice the drills, could I make a copy without drills?
I will solve it with the soldering iron and pieces of support of other impressions.
thanks for the design

How do you know how large to print the feeder so the diameter is right to receive the soda bottle you want to use?

Hi Dr Tom.

Printed in PLA, the feeder fits common soda bottle threads in the US and elsewhere that use the PCO-1881 standard. For ABS I would increase X and Y by 1% because it shrinks. If you need a different bottle thread I could design a version for it, but it takes some time.

If you are concerned about sizing, you could split the model using netfabb Basic to isolate the threaded portion which would be a quick print. Then you could test fit, measure, and calculate a scale factor if necessary to achieve the best fit.

I am using PLA as well. Something must have happening in the "sizing" function. I'll need to do an enlarge and test a new one as you suggested. I am planning on using a 20 ounce soda (Coke) bottle. The item printed out too small for the soda bottle.

Thanks Gazorpa, I need to to make a bird feeder with my son for school and we used your design. Way cooler than a pine cone smeared with peanut butter LOL.

You're most welcome, Kevin. Glad you like the design.

I'd love to see a picture of it printed or hanging, if you can take one. Thank you!

Very Nice Thanks for sharing

Looks like a great bird feeder!

However an acetone vapor bath for 2-3 hours?!?? Not if you do a true vapor steaming, it sounds like you don't boil and create a real vapor bath. The most I leave it in is for it for the vapor to rise enough to treat the entire surface plus maybe another 5-10 second.

A regular vapor bath without heat can take hours, when you use heat it takes only seconds. Be careful how you heat acetone, it is extremely flammable. And the vapors toxic, do it outside.

Thank you, thank you.

Still learning about acetone treatment, so I took out the time recommendation. Probably going to stick with an unheated process for small items at home for safety.
