This print protects the threads of your lathe spindle when you are using accessories mounted in the MT3 spindle bore. This is for a 9x20 lathe (or any other lathe) with an M39 x 4mm spindle thread.
I also included a test print piece which can be quickly printed out to test fit on a lathe.
If you want this for a different lathe, leave a comment and tell me what lathe you have, and I will prepare an STL file. If your lathe is not on the list at the link below, you will need to provide required measurements (note "D" and "E" measurements are not needed):
