looking for pre-fabricated rail supports and delrin rings
According to the instructions:
"Pre-fabricated rail supports will be available for purchase separately from a kit."
"Pre-fabricated rings will be available for purchase separately from a kit."
I guess they are still not available for purchase, at least I couldn't find them on contraptor.org.
I couldn't find any by internet search either.
Anyone knows a source I could by some from?
