Rotate 90* to print from base- no need for supports or raft
Why bother hooking up two fans when one works just fine? Not too much air to cause bed heating issues, enough air to keep your pla prints clean and solid.
This is a cooling fan duct designed to work with my RepRapGuru Prusa I3. Take out the bolts that hold the extruder heatsink on and rebuild from the motor-2 washers-extruder housing- black heatsink- cooling duct- spacer (already on the bolt).
While you have this apart it is a good time to tighten any loose internal bolts that may not have been torqued down from the factory.
