Polarstar Kythera Spacer Kit

thingiverse

Four differently-sized spacers to fill in space on the Polarstar Kythera HPA engine. They're a tight fit into the cylinder, but vastly reduce the air space inside. I haven't done enough testing to tell you which to use for which barrel length, so you're gonna have to work that out. If you print/use these, please let me know how it comes out. Leave me a comment with your barrel length and which spacer worked out best!
