Glass Bed Automatic Cooling System REMIX

thingiverse

This is a remix of Thing 4245339, yet I made no alterations whatsoever to any original files included here. I printed it unaltered and began assembling it on my printer as designed, but as I scrutinized it, realized virtually all the cooling air would be flowing directly past the glass bed plate. I created two components to add to it (Fan Pedestal and Fan Trigger Mount) to secure the system with on my Geeetech A30. I insert an end of print script in every one of my prints using the non-extrusion Gcode move command (G0 YXXX) to shift the bed to its maximum Y travel limits at the front. Once the bed reaches that point, the micro switch (with the Fan Trigger Mount I designed) activates the bed rollers underneath, turning on the fans which now aim directly at the center of the glass bed. Like the original designer, I used fans I had readily available, which just happened to be 5 volt 40mm fins. I simply connected them to my 5 volt buss that powers my printer's extruder brush cleaning system (located on the right side) as well as the Octoprint server.
