Imperfect Catapult Small Plane

At the beginning of 2023,
I got my first 3D printer,
Prusa MK3S.

March 31, 2023
I published my 3D printing debut
"Hand-thrown Propeller Plane"
on Printables.
Since the flight effect was far from what I expected,
I gave up.

June 1, 2024
I released its second version on Bilibili
"Imperfect 3D Printed Hand-Thrown Airplane"
I tried some different models

June 15, 2024
With the help of netizens from Bilibili
upgraded to the third version
"Imperfect 3D Printed Assembled Airplane"
You can try to improve the impact on flight in sections

July 27, 2024
Under the encouragement of netizens on Bilibili
A catapult was added and some minor upgrades were made to the airplane
The fourth version was launched
"Imperfect 3D Printed Catapult Airplane"

I have tried and failed along the way.
Every time I have made a little progress,
but I can never achieve what I imagined.
Therefore,
I have created this "imperfect little plane" series.

Now my printer has been changed to A1.
Let's continue the challenge here
and see what it will eventually become.

Let's fly farther and farther.

This is the 草色星球.
See you next time.
