Wonderful stuff!!!
I bought a Elegoo Neptune 4 Pro July 2023 and have printed a number of things, using STL files I got free or paid a small sum for, I have printed quite a number of WW1 aircraft in 1/72 scale for wargaming.
But there's things I want that there's no STL file to be found, so I'm trying to learn FreeCad. So far I've made a few simple parts for my model railroad but I'm having a hard time learning the program to make more complicated parts. Back in the early 70s I was a draftsman, but all we had was pencil and paper!!! This CAD stuff is kicking my butt!
So kudos to you, that's some nice work!!!
