Delta Extruder Assembly

thingiverse

This is a delta extruder assembly designed with the following in mind: 1. Maximize z height. This means mount the rods as close to the tip of the nozzle as possible. The downside of this is one-at-a-time prints will have to spaced out more. 2. Auto-bed level compatible. It is critically designed to minimize the distance between the nozzle and the touch leveler (triangle lab model). To achieve this, the ABL device is actually mounted at a 45 degree angle so that when extended it is only 3mm from the extruder. Delta printers are EXTREMELY SENSITIVE to any effector tilt, so this is really the only way to leverage a bl touch (unless you can achieve some pretty exotic tolerances with your build). Even mounted this close, you will need to ensure the effector is extremly level. So far, using the bltouch at an angle has not been an issue for me, but your mileage may vary depending on your build plate material. 3. Easy assembly. You simple thread a M3 60mm rod through each side, add a spacer, slot the fisheye, another spacer, then bolt it up. I purchased here: https://tinyurl.com/msudvuh8. Carefully clamp the rod in your drill chuck, then just drill it in. 5. Extreme cooling capacity. It supports TWO 50mm blower fans for serious cooling if you need it. 6. direct-drive compatible. You can use a nema15 with an OMG extruder configured as a direct-drive. Delta printers are not usually direct drive, but that's generally because people think of printing FAST when they think of delta printers. But if you're willing to slow down you can print direct-drive reasonably well. Note, this is only designed for use with a volcano extruder. I use and highly recommend this aluminum heater block: https://www.amazon.com/gp/product/B08NV8XL4G/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 I also highly recommend printing with ABS or other high-temp filament.
