This is a piece of the front transmission of the JJRC Q39. One of the two side supports needs to be modified to be inserted in the axis. To insert the pin, an upper part of the lateral support was removed and then glued.
While the main pin can be glued (obviously it is temporary).
I'm planning some changes, as soon as I complete the work, I will upload the file.
Print it with small nozzles.
Rotate the project of 90°.
