What this model does it when you put the outer ring onto the screw the ring will move one way and suddenly start moving the othe and then again and again its very fun to mess with and it only takes 1 hour and 28 min the reason this is the model you should print is because 

First: this is a quick print with just one hour and 28 min depending on your printer. 

Second: the tolorences is very big so it should work on any printer, I used to have a ender so I know how frustrating it can be if the tolorences is built for the bambu lab printers.

Third: when you print this model it helps me a lot when it comes to making more awsome models also a boost would be even better to help me make better models.

Fourth: This prints with very little support matterial so little fillament is wasted👍
