thingiverse

Dec 12, 16 - Update. Comments raised concerns about adapter fit. Enlarged opening and added extra space to ensure a perfect fit even at 0.2 mm printing resolution. A new version has also been created for the Cobra Fan with a horizontal fan mount. The -23 version is designed for vertical fans, while the -39 version accommodates horizontal fans. Sep 11, 16 - Updated design based on comments and added a slot to ensure compatibility with both fat and non-fat versions of the Cobra Fan. Use version 9 for optimal results; previous versions are available as references. This mounting adapter is specifically designed for use with the Cobra Fan on Wanhao Duplicator I3 V2.1 or earlier models equipped with the Wanhao 2.1 upgrade kit. The X-axis aluminum bearing blocks have been replaced with wider plastic ones, requiring a spacing adapter to maintain the original position of the Cobra Fan. Two M4 bolts (at least one) measuring 24 mm are necessary for secure mounting. Important Note: Use only M4 bolts up to 24mm in length to prevent lifting the plastic bearing bracket off the X-axis metal mounting bracket. Print Settings: Printer: Wanhao Duplicator I3 Rafts: Doesn't Matter Supports: Yes Resolution: 0.1 mm Infill: 40% Notes: This adapter can also be printed at a resolution of 0.2 mm. For added strength, print with 40% infill.
