I know a bunch of people are going to be getting shiny new i3 clones (Monoprice Maker Select or Wanhao i3) for Christmas this year, and I wanted to share an amalgamation of 3 different components that I put together.
The goal is to let you print just one part in order to rear-mount the fan on your Duplicator i3 V2.1 instead of stacking a bunch of adapters and rigging it up. This will not fit older versions of the Duplicator/Maker Select.
This cobra cooler accomplishes three things that weren't possible before:
It allows you to use the stock 40mm fan that came with your V2.1 i3
It mounts to the plastic bearing block that comes on your V2.1 i3
It's a one piece design that mounts rigidly with one 16mm M4 screw
Big shout out to tahustvedt for permission to share a derivative of his Cobra Cooler:
Also to PerN84 for the nice fan adapter piece:
And to raymnli for the fan adapter block:
I used a 4 x 16mm allen head screw to mount, but you could use a hex screw or philips, all would work the same (philips might be easiest).
Wall thickness 0.8.
Support overhang angle 55 degrees
10% support density
SUPPORT TOUCHING BUILD PLATE ONLY!
