Oh wow I was not aware. Thanks for sharing. Might have to start annealing my cans.

Ditto to everything @kopsis said except the part about annealing. Yes annealing will help. But I’ve had more noticeable strength improvements from moisture treatment over annealing -particularly layer adhesion. The wet sponge in bag method for a few days works quite well.

If you have the time and equipment to do both annealing and moisture treatment, do it.

 
 
 

This thing gets the OP9 nearly movie-suppressor quiet. Also keeps the can cooler to help during rapid fire. Also dropped the STEP file so people can remix it to position the nozzles optionally for other cans like the FTN4

In terms of models I recommend the APB3 on the bambu app. There may be a reupload on Odysee. The only mod I did was print the pin out of pacf SIDEWAYS instead of vertically. Good luck

Ser, just wanted to say thank you for you work putting these together consistently. Grateful to have been featured this latest edition but even when my designs aren’t, I enjoy catching up on things I missed when these come out. Especially valuable now that Reddit is dead to us, making the information more scattered

I’ve never heard of legit decibel readings for the ftn cans (or any 3dp can I know of lol). The problem is getting ahold of a decibel meter that can measure quick enough pressure impulses, and they are thousands of dollars. Phone microphones just don’t respond fast enough to the microseconds long pressure waves of a gun shot. Would be amazing to develop some sort of diy way to just ballpark it though - maybe some bursting pressure caps of increasing toughness… can’t be that hard considering the big magnitude difference in pressure between even eg 130 and 136 db

The tester who ran it on his psa rock said it cycled well. Chat on matrix?

It uses the same outer toob and adapters as the OP9, but optimized for smaller bores. Off-axis bore means no need for suppressor height sights.

Also, LOOK MA I CAN POST URLS NOW
