💥 UPDATES 

Thank you for all the feedback! I am constantly working on improving this design based on your comments. I've just uploaded a new print profile with an updated model.

Version 1.3 (latest)

• Screw assembly (no glue required).
• Reduced overhangs on the tail fin for cleaner and easier printing.
• Bearing shafts optimized specifically for Bambu Lab store 608ZZ bearings (EA027).
• Now printed in PETG (for better durability and weather resistance).

Version 1.2 

• Stronger bearing pins: I improved the strength of the bearing pin connectors. They are now printed separately and laid flat on the build plate, which makes them significantly stronger.
• Improved bearing mount: I slightly tweaked the bearing connector that screws into the Main Body so it holds bearing more securely.

Version 1.1

• Split the longest part: The tallest piece, which was prone to detaching from the build plate, is now split into two pieces that screw together.
• Tail nut added: I added a nut to the screw-on tail to make vertical alignment easier and more reliable.
• Improved threads: I fixed the tolerances on all the threads for a better fit.
• Note: I also printed this version in a different color scheme!
   

Project overview 

Another project for my windmill collection! This time I put in a lot more effort and designed something bigger, but still fitting on my A1 mini. If I eventually buy something bigger, I'll design an even bigger one! 🤣

I decided to go with white accents, so to minimize unnecessary filament swaps, it's best to print the parts on 4 separate plates. However, if you want to print it in a single color, everything will fit on one plate, even on an A1 mini.

To make this windmill, you will need:

• 2 x 608 ball bearings
• 6x M3x6mm screws 

Important notes: This is a very demanding print, so before printing, I recommend cleaning the build plate so you don't have adhesion problems later on. If you don't fully trust your printer to handle it, I recommend splitting the print profile where I arranged everything on a single build plate into multiple plates. Otherwise, if you experience bed adhesion issues, one loose part could fail and ruin the entire batch.
