This remix contains all 8 variants of the boltbase (locked, unlocked, nut, no nut, left and right) with ramrod as .stl and .step. The little cylinder is meant to be printed in another material as a support that you drop in during printing (add a pause at 3 mm height).
Keep in mind that this is untested, as my hardware kit hasnt arrived yet and it may take some time until I build the blaster.
The author remixed this model.
Some Cynthia kits do not include a metal ramrod, instead you print it yourself. I combined ramrod and boltbase (8 variants) which saves three screws for the ramrod and you dont have to align it.
