This is a remix on Novice Expert's fan duct system to better fit the R1 printer. The front duct now has a cutout on the left side to allow it to fit properly on the x carriage without pushing against with the x end stop switch. The rear duct Has been slightly shortened so that it no longer comes into contract with the heater block. The tolerance with the fans as also been fixed. These will print ready to fit a 40mm fan straight off of the bed. These as well as a few other overall changes to the design.
See instructions for printing details.
Big thanks to MarquisJohnson (Novice Expert) for the original design which not only looks great, but allows these to have a near perfect fit onto the x carriage.
Ok you can print this in just about anything, although I would recommend you use something that is not ABS and can withstand higher temps. PET+ would be best, but if nothing else you can just use PLA
Print with minimum supports. You only want supports that contact the glass. Supports for the bridges on the inside of the duct have been drawn into place. Just snap them off when the print is finished.
Print on a 20% infill
Most importantly if you have a RoBo printer, do yourself a favor and go check out Novice Expert on youtube
