Hi folks!

I built my own laser engraver and want to share it with you in this 'ible'! I made it with the help of my 3D printer.

I saw this one http://www.banggood.com/500mW-Desktop-DIY-Violet-L... and thought i could print the acrylic parts. This is why i made it.

My working area is:

X 265mm
Y 345mm

But it depends on the aluminium profile you´ll buy.

My parts are:

Frame

- 2x 440mm

- 2x 320mm

X axis

- 370mm

.stl Files and DXF

I first printed some parts vertical, but the motor holes were some kind of comressed then. It is much better to print them horizontal...

2. screw the motors on the parts

3. put the x part on the axis

4. add the side parts of the x axis

5. assemble the frame

6. put the x axis on the frame
