Once you are launched onto the website, you should start to enter a search term. This is where you can really start to dig deeper into what YOU want to build.

For Example:

In the search bar I chose "Tea Bag" which led me to all these amazing things!
The coolest part about Thingiverse is there a bunch of different ideas that you can pick from, so no need to stress. The "Tea Bag" is that it had 29 different ideas.

Now that you have your .DXF file on a thumb drive you are finally ready to cut. Insert your thumb drive into the USB drive of the computer that is hooked up to the laser cutter you are using. Then go on the laser cutting software and click "file" then click "import." Once you select that button a screen will pop up with all the files in the computer on it. Find your thumb drive and click on it. Once your thumb drive is opened up find your .DXF file and double click it to import it into the software.

Test and Cut

Now that your file is imported you are almost ready to cut. First step toward cutting is ensuring that the file imported in the right scale.

If it didn't: highlight all pieces in the file, hold down CTRL on your keyboard and drag the corner to make the pieces larger.

If it did: put a sheet of wood into the laser cutter, click "download","del all", and "download current." to test and make sure the wood is positioned in a safe way hit "esc" on the machine and then hit "test"

If the tests go well and your wood is positioned correctly you can close the laser cutter hatch and click "start."

You are now laser cutting.

Assemble

Now that you have patiently waited for all of the pieces to be cut out you are ready to assemble them.

Simply apply wood glue or hot glue as needed to the pieces and fit them together like they are cut to be put together.

If you make an item with interlocking teeth on it you may not need glue, but instead just press the teeth into its matching pair and it should stick together great.

Good job, you did your first laser cut!
