Customer Reviews
The gears spin so smoothly! Print-in-place with zero assembly and it works perfectly. Great desk toy and teaching tool.
Bought this for my engineering class. Students love it. The 4:1 gear ratio demonstration is worth more than any textbook diagram.
Really cool mechanism. Took a couple of turns to free up the gears but once broken in, it spins beautifully. PETG Crystal material looks great.
Mesmerizing to watch and play with. The transparent PETG lets you see all the gear interactions. Perfect fidget toy for meetings.
Solid print quality and clever design. The planet gears are beautifully executed. Wish it was a bit larger for better visibility of the mechanism.
Third one I've bought — they make the best gifts for engineer friends. Always impresses and the price point is perfect.
