Playskool replacement Busy gear toy remix

thingiverse

Since the original post and a subsequent make both mentioned a tight center race fit and needing to file, sand, or acetone the inner race, I just remixed the center hole a touch larger. Printed with .8 walls, 15% infill and it worked great right off the print bed. It's a solid version of the original shape that is a good shape match without the extra hub sticking out of the bottom. An exact shape gear match with the extra hub extension on bottom would require supports and have some waste, this flat bottom design prints without support of any kind and zero waste. It fit and meshed perfectly for me with zero trimming right off the print bed. Nice looking print mivanov,now it fits nicely too.
