Glass Bed Automatic Cooling System REMIX

thingiverse

This is a remix of Thing 4245339, however I did not modify any of the original files (which are also included here). I printed it unmodified and started to mount it on my printer as originally designed, but as I was looking at it, realized all but a tiny fraction of the cooling air would be blowing right past the glass bed plate. I designed two pieces to add to it (Fan Pedestal and Fan Trigger Mount) to mount the system with on my Geeetech A30. I insert an end of print script in all of my prints using the non-extrusion Gcode move command (G0 YXXX) to move the bed to the limits of it's Y travel to the front. Once the bed reaches that point, the micro switch (using the Fan Trigger Mount I designed) engages the bed rollers underneath, turning on the fans which now point directly at the center of the glass bed. Like the original designer, I used fans I had laying around, which happened to be 5 volt 40mm fins. I just connected them to the 5 volt buss I have for the printer which also runs the extruder brush cleaning system (right side of printer, also posted on Thingiverse) and the Octoprint server.
