Prusa I3 - Anyone recognize these plastic parts?

I have a used Prusa I3 and I'm looking to ID the source of, for the files for the printed parts. After looking at every extruder picture the search engines will send me, I'm not finding a match for that or the other parts.

The driven gear on the extruder has a hub pattern that I've only found on Herringbone sets (see picture).

Also seemingly unique is a 43/13 ratio on the extruder. It appears to be an Adrian's extruder but looking for confirmation from someone who knows on that as well.

Thanks!

I think the extruder gears are these: [www.thingiverse.com] (found by a quick search for "biohazard" on Thingiverse)
I'm pretty sure the extruder is just the standard Greg Wade's etc. for the i3, can be seen here: [github.com]

I belive you nailed it on both counts. I didn't recognize that as a biohazard symbol until you mentioned it.

Thanks so much!
