Description
and his fascination with the wind altogether fascinated me too.
//
So I made his design (with a few intentional alterations) into model that is easy (no support needed, custom brim already incorporated into the model) and quick to print. Every part except body (2 h) needs approximately 1 hour to print.
//
The wings are printed like a flat surface but are bend according to the main ribs when assembled. The wing span is 65 cm.
//
The body is designed so that is aerodynamic and lets the 4 screws that hold the tail and main ribs to the body to penetrate making it ideal for a variety of add-ons.
//
No additional materials needed (the wings are printed so that they are not able to loosen up, they are light, strong and flexible so they can be easely bended - ultra thin layer printing), just print all the parts, screw everything together (the wings are holding themselves tight to the main ribs even without the screws) add some nylon threads and make it fly!
//
I also added STL files Left wing_big and Right wing_big for printing the wings in one piece on large printers.
You only have to print the Left wing 1+2 and Right wing 1+2 set or Left wing_big and Right wing_big.

Print without support.
If you don't have the build height needed (180 mm) you can lay down the ribs and print them horizontally with support.
//
The wing are 0,4 mm thick so watch out when removing it from the printbed (although in my experience the are quite hard to break).
//
On the wings there are small circles (brim). It's there to better hold the print to the build plate. You can remove it after the print.
//
Ribs can oscilate a lot on the very end of the print. They are tall and slim so they can be easely knocked over. If you have problems printing the ribs, you can try lowering the speed on those layers that are higher up. Also, you can try using bigger surface area for the brim.
Material // I used PLA and PETG. PETG was better (flexibility)
Layer height // 0.15 (for wings - don't go over 0.4 or it won't print properly)
Layer fan // on (i had my off just to see if it can print without it - it can but it's messy)
Perimeters // min 2
Infill // 15 % in case of Body and Tail, down to 0 % for the Ribs and Wings
No support needed.
Assemble guide is included in pdf. format.
Printed parts, 18 (or less) M3 nuts and bolts and a nylon thread or something like that to hold and control it in the air.
The nylon threads are tighten to the main ribs between the two m3 bolts that connect the two parts of the main rib.
