How about making your own, and flying it EX? Is that an option for you?

I have a SkyRipper 29mm motor. I used Fusion 360 and put in the fuel grain deminsion and 3D printed ABS fuel grains. They work great.

the graphite nozzle is the problem

I wonder if one of the RCS nozzles could be made to work.

I wrote an email, I asked if they have nozzles compatible with I80 and if they ship to Europe

I am using ABS and not ABS + which has a lower melting point etc. I measured a factory grain and drew it up in Fusion 360 to print. It workEd good.
ok i have an open delta printer i have never printed ABS but it is a good opportunity to start.
thank you.
now I just have to find the nozzle
