This are optimal length extenders for very common drone transmitter (E010, H36, MakerFire and other similar drones). I've tried all kind of lengths but this one seems to be the best. This part goes between the transmitter and original transmitter knobs.
- Tolerances are just right, they are not too hard or too loose to put on the transmitter!
- Added fillet for easier attaching and fillet to make larger contact area to print.
NOTE: Make sure you orient file so that widest part is in the bottom - for good bed adhesion.
I've printed with 0.2mm layers, PLA, 40mm/s speed. :)
EDIT: 5 different pilots have this extensions and confirmed that this is actually the best size.
