Wanhao I3 V2.1 Cobra Fan adapter

Dec 12, 16 - Update. Saw a few comments about the adapter do not fit. I enlarged the opening and give it some extra space. Now even printing at 0.2 mm resolution, there is enough room. Also, I made an new version for the Cobra Fan with the horizontal fan mount. The -23 is for the vertical fan and -39 version is for the horizontal fan. Sep 11, 16 - Updated base on comment and added a slot. It should fit the fat and non-fat version of the cobra fan. Use version 9. Previous version is there as reference. This is a mounting adapter for the Cobra Fan to be use on the Wanhao Duplicator I3 V2.1 or previous versions of I3 using the Wanhao 2.1 upgrade kit. The X-axis aluminum bearing blocks are replaced with wider plastic ones. An spacing adapter is needed to mount the Cobra Fan and keep it in the same position as before. Two (at least one) M4 24 mm bolt is needed. No need to thread the bearing block as the plastic blocks already has the M4 nuts Note, do not use M4 bolt longer then 24mm as it will lift the plastic bearing bracket off the X-axis metal mounting bracket.
