Description

gear project Project Gear Set – TeacherGeekThese are not your average project gears. Before TeacherGeek, gears were often too expensive, too small or required hot glue (ow!) to attach to shafts. Movement was rigid, and the lines of kids with singed fingers in the nurses office felt like a mile long. TeacherGeek project gears are a class of their own. Featuring splined holes to push and rotates with a dowel shaft, they can be easily removed or changed as designs evolve and experiments expand

These are not your average project gears. Before TeacherGeek, gears were often too expensive, too small or required hot glue (ow!) to attach to shafts. Movement was rigid, and the lines of kids with singed fingers in the nurse’s office felt like a mile long. TeacherGeek project gears are a class of their own.

Featuring splined holes to push and rotates with a dowel shaft, they can be easily removed or changed as designs evolve and experiments expand (no hot glue necessary). They transfer impressive amounts of power, while remaining simple enough for elementary use. Whether in our tinker set or as part of a larger STEM, science fair or engineering project, TeacherGeek gears are the preferred choice.

Gear colors may vary.

The 40-Pack contains ten of the following sizes: 10 tooth, 20 tooth, 40 tooth, 50 tooth

The 4-Pack contains one of the following sizes: 10 tooth, 20 tooth, 40 tooth, 50 tooth

Definitely a tough toy
Color: Blue
This is one of the few toys my Boxer/american bulldog mix hasn’t been able to tear apart. He loves chewing on it and I love that he doesn’t chew on stuff he shouldn’t. I have such an issue with toys being torn apart the day I bring them home. I wish there was a safe way for it to have a squeaker since he loves squeakers but I don’t think that is possible.

Croc-sational
Color: Blue
My tough chewer is OBSESSED with Croc. Stands up well, small particles occasionally come off but this beats going thru 3 stuffies in an hour. Good value, easy to clean and great for our 91lb pitty

Withstands very aggressive chewing
Color: Blue
We have a very active and aggressive chewer. Items identified for aggressive chewers are “Gone in 60 Seconds”. This toy is amazing. It has withstood Jake’s many attempts to destroy it and is one of his favorites! It is not hard like acrylic but is hard rubber with some give decreasing risk of fractured teeth. Best toy yet!!!

Well loved
Color: Blue, Color: Blue
We just got this sweet girl from the shelter a few days ago. She's had this toy for 2 days and already chomped off one of the legs. She does have other toys so she doesn't play with this one all the time but she does like it a lot! It's very hard and durable on the ends. But as you can see, it's not indestructible. She carries this little guy around the house like they're BFFs. It's super adorable.

Dog likes it, but is very hard material around smaller dogs when he is playing and running
Color: Blue
My 22lb dog loves this chew. We have owned it just for one day. He immediately loved it and he races through the house holding it in his mouth like a grand prize. I have concerns to the hardness of the ends of it, the material is very hard, and the tail comes to an end shape that could hurt other pets in a multidog home if it hit or stuck in them. I have two smaller chihuahua dogs, one who has lost an eye so this is something to be careful about with other dogs running with this toy. This may not affect a one dog home. Best to observe the dog while playing with it around others.
