Robo 3D Dual Fans with IR sensor mount by warpster

Last crawled date: 3 years ago

This is a Dual Fan setup for a Robo 3D with the Hexagon Hot End.
There are 4 fan enclosures included, the front, rear and a rear with 2 mini IR sensor mount, one adjustable mount and one fixed. All 4 have a slider option to modify air flow. I designed this to be used with the Noctua 40mm NF-A4x10 fans if you plan to use other fans you will need to modify the fan mount to allow screws in the top fan holes (STEP file included). For the Noctua there are two pegs at the top and holes for screws for the bottom of the fans, the pegs alone will hold the fan. I've included screens for the fans along with spacers for between the IR board and the mount and a template for aligning the sensor. Use two M2 X 6 machine screws and a nylon insert lock nut for each. I had a regular nut vibrate off prior to using them. These will work on a stock Robo 3D R1(+) without modification.
I printed with PLA using S3D and supports are required for the fan mounts, other parts need no supports.
The Guide.stl is a light guide, printed in clear, for the LED which now faces to the rear, this is experimental and I may change this in the future. New curved light guide added.
Note: I've updated the spacer to make it a little thicker and added a mini IR sensor version that has a fixed mount with captive nuts. The z offset using this version should be -1.99 to -2.1.
