Stealth Press ZERO MGN12

I really like the idea of the Stealth Press Zero but since I do have a lot of MGN12 rails lying around, that I won't be as likely to use in the foreseeable future, I remixed the files for that rail size. Current design is printed and tested with 220mm MGN12H in mind, different length could be adapted pretty easily.

If there is more interest in the other tool holders, or different rail lengths, just drop me a message and I'll get on those in the next couple of days.

Almost all elements have been altered - except a few parts on the tool holder.

Remixed almost all parts for MGN12h compatibility
