60mm planetary gear with five planets. Printed with 0.3mm clearance, it initially felt like a solid block but broke loose easily enough with a hex driver twisting the sun. Ran it with a drill for a few seconds to smooth out the action. Very interesting way to print bearings - it has the axial thrust resistance characteristics of needle bearings, but with no need to assemble bearings inside a race.
@Mark_Durbin Yep, that’s the one. Sorry, should’ve included that in my description, huh?
@Patrick_Ryan Ah, no harm done! I assumed you forgot. I can see the EL in the side 
@Mark_Durbin Yeah, I wasn’t exactly hiding its origins, was I?
pht. it’s so well known now amongst the 3d printer crowed that linking isn’t really necessary.
