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

I'm thinking about it

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.

 

[stefanoP]

the graphite nozzle is the problem

the graphite nozzle is the problem

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

Single-Throat Nozzles

NOTES: 1. All nozzle throats may be opened and/or enlarged using high-speed steel drill bits. 2. Any other machining should be accomplished on a lathe with carbide cutters.

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

Why not contact the I80 manufacturer for parts?

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.

I'd suggest contacting Tom at Contrail Rockets. He has 29mm hybrid hardware listed. If you know the nozzle throat size, you could probably have a graphite nozzle made for you by Fisher Research.

ok i have an open delta printer i have never printed ABS but it is a good opportunity to start.
