K'nex Gearbox: Make Your K'nex Motor 6x Faster!
Intro: K'nex Gearbox: Make Your K'nex Motor 6x Faster!
Check out my Knex Army Knife too!
Hi guys, here are the instructions for my K´nex gearbox.
You can increase speed by approx. 6x compared to the original K'nex motor speed. It packs a punch, the box construction is very strong. I dropped it some times and only 1 thing came off. The gearbox is easily upgradeable to reach higher speeds, but my K'nex motor can't provide more power than what it's now. The gearbox is nicely hidden in a fairly small and strong box.
Pros:
- Colorful!
- Strong
- Compact
- Easily upgradeable
- Looks pretty nice
- 6 times faster rpm compared to the original K'nex motor rpm
Cons:
- Takes some time if you want to change something inside
- You need a pretty strong K'nex motor
Tell me what you think, and don't forget to rate!
Well, let's build this thing!

The 3rd (and final) axle does not need the larger yellow gear on it does it? Seems the speed multiplier gears (large yellow drives smaller blue) finishes on the 3rd axle's small blue gear. The yellow gear should not do anything useful should it?
