3D printed stuff, showcase it here

3D printed a lot of drone propellers, mostly not good or to heavy, but finally found some that are very usable, so guy named Logan on youtube, link to his video and files is on my video

Lots of mishaps went on there ...

Some of the drones i have built, and more in the works, mostly 3D printed

You mean propellers?
Pretty damn well, none have disintegrated so far and mostly the smaller ones stay intact when bumping into something while spinning, it takes a bit of effort to break them, and that is mostly due to printing direction.
Also i do not use PLA, ABS, HIPS, PETG, and lately PA6 Nylon.
The main issue are sanding them properly will improve efficiency a lot, and balancing them is a must sometimes.
Give it a try, you will be surprised how good they can be, just keep layer line longitudinally.
