Cooling Fan Duct For Wanhao Duplicator i3 V2.1 / Monoprice Maker Select

thingiverse

After reading online trying to diagnose some print quality issues I've been having with the Monoprice Maker Select (Wanhao Duplicator i3 V2.1), I determined they may be the result of inadequate cooling. My attempts to find something on Thingiverse that fit my printer all failed. There were a few options but they mostly used a 60mm fan or blower -- neither of which I had on hand. This uses the stock screws and 40mm cooling fan but I haven't refined the design yet so the screw holes aren't very robust. Don't force the screws or you may split your print. If needed ream the holes a bit and don't over-tighten the screws. The picture of my printed duct was taken after I used it for 30 minutes to print the cable chain link. I see no signs of it melting or distorting from the heat of the extruder. I printed this at low quality settings since I was anxious to give it a whirl. This is by no means a perfect design or the final version. I've never attempted a part like this and it's the first time I've used Fusion 360. At this time I lack the skill/talent/experience/knowledge to get the design I want into the software so I'll be improving this as my skills progress. Update 01/10/2017: As requested I've uploaded a version suitable for a 50mm fan. WARNING: Please check the screw spacing of your fan bracket before printing this. This only fits brackets with a spacing of ~30mm. I tested the original parts and printed them as shown without supports. The 50mm version is untested. It may not print as oriented or without supports, the part may not be level with the print bed, and I did not have a 50mm fan to get measurements from so I just did a Google search and winged it. If you're willing to give it a shot please report back so I can take it down, fix it, or give others the confidence to try it. Thanks.
