Summary

Useful accesory for RC planes - servo push rod lock (for those who don't like Z-bending connection). 4 parts set with custom brim, printed in PLA as shown on stl preview , layer 0,2mm, no support. Two stl files - for 0.8-1.0mm and 1.0-1.2mm pushrod diam. This is a tiny component, so depending on your printer precision, some additional sanding with a file may be needed. I tried several different solutions, this one works fine for me. At the stage of setting up the model, just slide on the O-ring (disconnecting possibility), but for flights I secure it with the drop of the glue.
