Hexagon hot end shroud for MakerFarm i3 i3v Wade's Extruder
The stock shroud provided with the MakerFarm hexagon-style hot end suffers in that it clips onto the heat tube of the hot end. This causes the shroud to soften and melt, often dropping onto the hot end aluminum block where the melted shroud often drips onto the print or print bed. The oversized fan and shroud also allow a lot of airflow to bypass the hot end heatsink, reducing the amount of cooling actually obtained.
Two alternatives to the stock shroud are provided here. Both use a 25mm fan such as a 3 CFM Sunon MAGlev MC25101V2-000U-A99 to exhaust heated air towards the front of the printer. Both mount to the front of the MakerFarm Wade's Extruder base using the same mounting holes as the stock 40mm hot end fan.
File hex_shroud_flush allows the 25mm fan to mount flush to the shroud bracket. File hex_shroud_angle10 adds a spacer block that tips the fan upwards by 10-degrees, minimizing the possibility of fan exhaust from hitting the front of the heat bed.
Note that the rear shroud component differs between the two designs. The flush mount style has a round inlet hole to match the fan. The angled mount has the round inlet on the angle plate, and is designed for a better fit with the angled fan mounting screws.
These shrouds are intended for use with the MakerFarm i3/i3v X-axis carriages that use a wood shelf along with an aluminum grooved plate for the hot end mount. Most corners are rounded for consistency with the MakerFarm design style. Suitability for other hexagon hot end applications has not been verified.
