Line laser pointer and normal laser pointer

prusaprinters

<p>A housing for a line laser module and another housing for a normal laser module to create a (line) laser pointer. The modules are from ebay, you can buy them here: <a href="http://www.ebay.de/itm/Red-Line-Laser-Module-5mW-650nm-Focus-Adjustable-Laser-Head-5V-/181955353142?hash=item2a5d625a36:g:v~MAAOSwNphWZsaK">http://www.ebay.de/itm/Red-Line-Laser-Module-5mW-650nm-Focus-Adjustable-Laser-Head-5V-/181955353142?hash=item2a5d625a36:g:v~MAAOSwNphWZsaK</a> and here: <a href="http://www.ebay.de/itm/Mini-650nm-6mm-3V-5mW-Laser-Dot-Diode-Module-Red-/272058069247?hash=item3f57ecb0ff:g:BXEAAOSwuTxWCl70">http://www.ebay.de/itm/Mini-650nm-6mm-3V-5mW-Laser-Dot-Diode-Module-Red-/272058069247?hash=item3f57ecb0ff:g:BXEAAOSwuTxWCl70</a><br/> The batteries I used are of the type AG13.</p> <p>Assembly:<br/> You need 3 PCBs, two of them each 3x3 slots with a single pin soldered to the centre. Remove the black insulation from the pin and bend it downwards. These PCBs are used to connect the batteries (see pictures). There is a hole through the battery slot to connect the cable to the back of the batteries. The other PCB is simply for the switch. The triangular holes in the battery slot are designed so you can get the batteries out easily.</p> <p>The line laser module needs more power than the normal laser module, therefore, there are three batteries for the line laser and two for the normal.</p>
