My family got a 3d printer! We have being fervently printing many practical and fun things. I designing the things in Tinkercad (and sometimes import parts from Thingiverse), and then we export them to the 3d printer to be printed. Here are some example of things we’ve printed:
If you want to 3d model, you don’t have to buy a 3d printer. You can create an account on Tinkercad (its the most user friendly platform I have found) to just make models without printing them, or you can find a public 3d printer near you if you really want to print your things. Have fun modeling!
