Forgive me, I know the following information isn't chicken related...but it has wings...3D printing, that is seriously cool. I have been able to source whatever I have needed for a long time. I live in fear that something will not be available some day. Therefore I buy some things when I see them. For example I bought a steering column switch assembly several years ago when I saw it on ebay.

My son designs 3D airplanes...he is very talented, everything he does is self taught! Here is the latest one he did...it's completely his own design, he's finally finalizing the design...Covid kind of messed things up! You can see the others he's done on his YouTube channel! https://www.youtube.com/channel/UC7aSxYosPz9UiaV0za61nVg
His Flapjack won a competition it's a WW2 plane! The people in the remote airplane community are patiently or impatiently waiting for him to release the build plans for his current plane - The Revenant MK IV! He wanted to keep the landing gear, but hasn't found any of good enough quality! I have expect him to set up to make and sell his own someday!
The Maiden! The picture you see here is a computer rendition...when you start the video you will see his first prototype!

Just have to show his Flying Flapjack, this was flown at Flight Fest in Ohio
