Bolt Knob M6 for Bolt Action Rifles

Was searching for some printable bolt knobs, but did not find a suitable  one for me, so I designed two models.

These Bolt Knobs require you to heat insert a Ruthex style M6x8x8 brass thread, as seen in pictures.

Print in PLA is more than fine enough, but feel free to use any material you like.

I had zero issues, just fyi: If you should have bed adhesion issues, just add a brim. 

These fit perfectly for CZ 457 and Bergara B14, but will fit any bolt handles that are threaded M6x1.

Let me know what you think!
