These sticks are primarily designed for the graupner MZ12 RC transmitter, although it might work with any transmitter utilizing an M3 nut design.
I printed these without a raft, but it might be a good idea to use one if you have some adherence problems.
To assemble it you just need to insert an M3 nut in each stick (it's a tight fit so no glue required).
Enjoy
