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.
- Easily upgradeable
- Looks pretty nice
- 6 times faster rpm compared to the original K'nex motor rpm
- 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!
