How do you do a 3D printing?

3D printing: to do a 3D print you need a 3D printer and filament for said printer and software to make your model -- a good software is Tinkercad -- and another software that connects to your 3D printer -- a good software is Up Studio -- once you get these things you can start 3D printing. to do this you will need to open up Tinkercad and click create new design, you should now be looking at this:

on your right had side you have the shapes you can use to make your model. To do this you just drag and drop. If you click on the shape you should have some options come up like this:

using this you can change the colour of your shape and the width, length, height and radius or you can do this by clicking on the little squares and dragging. To make a hole on your shape you pick the shape you want to make your hole with and the click the hole option on your right side so it now looks like this:

or you can use Ctrl G now your shape should look like this: 

well done now you have a hole play around a bit more and make the shape you want then you can export it to up studio then you can print it hope
