CNC Laser housing V2.2 for 12 mm diameter laser Diode

2000mW Diode is working now - added a picture of an engraving on a aluminum plate. Perfect results with automatially on/off triggering directly via Gcode - I'm using "Simply Cam 2" a really simple but very useful 2D CAM Tool.
All running with WINPC-NC USB on my 3 Axis CNC machine
##############
ordered a 2000 mW 445 Diode and need a improved cooling for the diode.
used a heatsink for LED and redesigned my first version to place a 30mm fan in the housing blowing the air directely through the heatsink for perfect cooling of the diode.
##############
added some Versions - one with a 5 mm higher body and rotated fan mount - and one without the mountig cylinder - easier to mount it on different machines for people who are not abe to edit STL :)
###########
finally I designed one with a cooler from side with an integrated duct - just to play around with some ideas

Diameter for moutig fits for 43 mm "Kress Spindle"

need support for printing
in slic3r a 4mm rectangular grid is a good choice

have fun
