EUDAX 82 pcs Plastic Gear Package Kit DIY Gear Assortment accessories set for Toy Motor Car Robot Various Gear Axle Belt Bushings

My daughter used them for school engineering project

Ordered this to fix an old toy, did the trick, reasonable price.

I prototype a lot of things and these parts are good enough to "make it work". They would be fun for kids or just tinkering, but if you're looking for something that will last, this is not it. Great for what they are, cheap gears. I'll buy more!

This save my daughter in her school projects. It has all the things needed. Thanks for the person who recommended this to me.

I bought this set hoping to use these gears on a small project, but the description for it is vague and confusing (describing the spur gears as pulleys, for example), so I used the images provided to guess what size and kind of gears were included. I assumed it had multiples of similar sized gears, but unfortunately it doesn't have more than 1 of each size of the gears provided. A more accurate description would have saved me time and money. Returning it seems pointless, as the product is barely described at all, let alone whether or not it's actually correct. Thankfully, it's cheap so I'm not out too much money.

I wired a couple of 9V batteries in series to power the little motor with a worm gear and a gear on the rearaxle and used the axles and tires from the kit to make a pretty cool derby car for the "anything goes" class of racing. The race is tomorrow, I hope it stays on the track. This is a fun kit to be creative with any engineering project I suppose.

The wheel alone cost 9 bucks on amazon, but this comes with the wheel (which have a rubber like tread) and multiple axles sizes, plus and puller and installer tool. The only thing it didnt have last time i bought it, and I may have just missed it was a 1mm id gear, but thats no big deal as I have about 5 now from other sets. Everyone wants to buy the rails individually too, BUT this set has 2 rails and 4 wheel, its the best deal on Amazon right now. Im working on hitting 30 mph on a mini drag race car so ill be buying more as time allows the builds. Great compliment to the EUDAX 24k RPM motors they sell too. Can also get this kit and motors for a few dollars more.

Good, lots of different types of wheels. not really clear what they are for, would benefit from more instructions. For instance some colors seem tighter than others, are the latter supposed to be free spinning ? Another point is that they aren't very solid, and definitely don't stay in place when used with a high torque motor.
