Improve cooling with a dual 5015 fan setup.
-no air dumping down on the part when you don't need it [PETG, TPU]
-20g lighter than the stock setup
-clear view of the nozzle, easy to clean up stray filament
-exposed hot end. Keep kids and curious pets away.
-if you use Cura > Print Sequence > one at a time, the fans may crash into existing parts
What you need:
2 5015 radial fans
2 3x25mm nuts & bolts [nylon/metal]
rewiring materials [soldering iron, shrink wrap, 2-pin connectors...]
dial indicator with 8 or 9.5mm stem
Leveling the bed:
-heat the bed up to normal operating temperature
-press fit the dial indicator into the mount
-run the included level.gcode
-after homing there is a 10 second pause for zeroing the indicator
-there is a 5 second pause at each corner for adjustment
-it goes around twice
-tweak the gcode to match your workflow
***remove dial indicator before printing
This process levels the bed but does not set the correct distance between the nozzle and the bed. Test print to get the right height. Try using thingiverse.com/thing:2425796 for easy adjustment. Turn each knob an equal number of teeth to maintain a level bed.
*added the original Fusion 360 files.
Use 5 walls [perimeters] for strength.
The part cooling fan clicks into the mount and is secured with a bolt. Attach the mount to the X carriage with the original hardware [M3 bolts]. Rewire the fans.
