Qidi Tech 1 LED Dual Fan Duct

Update December 10, 2018: Per request I have lowered the bottom of the original duct by 2.5mm and created a new model called Lowered LED Dual Duct. I have no way of trying this out and have no idea if it will fit the X-Pro as desired. Update November 21, 2018: Per request I have extended the opening by 5mm and created a new model called Extended Dual Duct. I have no way of trying this out and have no idea if it will fit the X-Pro as desired. September 12, 2017: This design is a cooling duct/LED Light for the QIDI Tech 1 printer with dual extruders. Originally I created the Tech 1 Extruder Light, https://www.thingiverse.com/thing:2389917 , but the design was flawed and was too fragile. Also, it didn't support dual duct cooling. I liked the idea of ChrisX35's Dual Extruder Fan Duct, https://www.thingiverse.com/thing:1542849, but didn't see a good way to attach LEDs to it. Using some ideas from both the Extruder Light and the Chris's dual duct, I created a new design that has dual duct and LED lighting. The duct requires one m3x16 and one m3x20 socket head cap screws. One screw attaches to the cooling fan plate and the other replaces the screw attaching the carriage to the extruder block. The LED strip is mounted and folded at the corner to get the 90deg turn. Super glue is applied after the LED strip is mounted with the adhesive backing. The super glue is applied along the edges of the LED strip and an accelerator is sprayed to very quickly set the super glue. You can quickly press down on areas of the strip that are not flush with the base. It only takes a couple of seconds for the glue to set after spraying the accelerator. Similarly you can route the LED supply wires to the edge of the duct using super glue with the accelerator. The duct must be printed with supports from the base, no internal supports are required except I used them in the horizontal holes. Also supports under the fan mounting rectangle are needed. I used the supports at a 45 degree angle with support infill percentage of 40%, extra inflation distance of .4mm and 1 support base layer. I used polycarbonate filament. I made a version with ABS but saw some effects of the high temperature so I changed to polycarbonate, printed at 240C. I used a 12v supply that also feeds power to my enclosure fan. I should have been a little more careful with the placement of the LED strip. One of the LEDs ended up where it was more visible, so I glued some small pieces of filament next to the LED to block the bright light from normal viewing angles. This could be done for all the LEDs if the edge viewing is a problem. This was modeled with Fusion 360 and sliced with Simplify3D. 0.2mm layer height, 4 top and 3 bottom solid layers with three perimeter shells. 0.4mm extrusion width Materials Required: 1-m3x16 hex socket head cap screw 1-m3x20 hex socket head cap screw 12V DC White LED ribbon; I used https://www.amazon.com/gp/product/B00WQFP3AO 12V power supply Wire and connectors Super Glue Super glue accelerator; I used https://www.amazon.com/gp/product/B0166FFCCS Polycarbonate filament; I used https://www.amazon.com/gp/product/B071D312JN/
