- Hornady Rotor or benchrest Rotor
- Hornady lock n load bushing adapter (1.25"-12UNF to LNL Bushing). In case you don't have one, print the "stand_die_thread.stl" and screw the die body directly into the stand.
print "thread_test_block_1_25-12UNF_v1.stl" to check if your printer calibration is right.
Use 400-600 grid sandpaper to smooth the rotor housing (yes it's to small, that's on purpose)
